 TextFormField is auto-validating itself without updating its content

`TextFormField `is auto-validating itself without updating its content causing the user to see red fields after he enter in a page containing +6 TextFormFields.

## Steps to Reproduce

Run the following code:

```dart
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String _validateSample(String value) {
    if (value.trim().isEmpty) {
      return 'This field should not be empty';
    } else if (value.length < 4) {
      return 'Minimum allowed is 6 charaters';
    }
    return null;
  }

  @override
  Widget build(BuildContext context) {
    final style = TextStyle(color: Colors.green);

    return Scaffold(
        appBar: AppBar(
          title: Text(widget.title),
        ),
        body: Padding(
          padding: const EdgeInsets.all(32),
          child: Column(
            children: <Widget>[
              TextFormField(
                autovalidate: true,
                controller: TextEditingController(),
                keyboardType: TextInputType.number,
                decoration: InputDecoration(
                  hintText: 'With autovalidate: true',
                  border: OutlineInputBorder(
                      borderRadius: BorderRadius.circular(8)),
                ),
                validator: _validateSample,
              ),
              Padding(
                padding: const EdgeInsets.symmetric(vertical: 16),
                child: TextFormField(
                  autovalidate: true,
                  controller: TextEditingController(),
                  keyboardType: TextInputType.number,
                  decoration: InputDecoration(
                    hintText: 'With autovalidate: true',
                    border: OutlineInputBorder(
                        borderRadius: BorderRadius.circular(8)),
                  ),
                  validator: _validateSample,
                ),
              ),
              TextFormField(
                autovalidate: true,
                controller: TextEditingController(),
                keyboardType: TextInputType.number,
                decoration: InputDecoration(
                  hintText: 'With autovalidate: true',
                  border: OutlineInputBorder(
                      borderRadius: BorderRadius.circular(8)),
                ),
                validator: _validateSample,
              ),
              Padding(
                padding: const EdgeInsets.only(top: 16),
                child: TextFormField(
                  controller: TextEditingController(),
                  keyboardType: TextInputType.number,
                  decoration: InputDecoration(
                    hintText: 'With autovalidate: false',
                    border: OutlineInputBorder(
                        borderRadius: BorderRadius.circular(8)),
                  ),
                  validator: _validateSample,
                ),
              ),
            ],
          ),
        ));
  }
}
```

1. Without changing TextField values note
2. That the first three TextFields are showing validation error, and
3. Note that the last TextField is not showing the validation error.

**Expected results:** 

We expect that all TextFormFields don't show validation error since the user did not change its content.

**Actual results:** 

We see that the Fields with `autovalidate` set to true are showing validation error without its content being changed.
