A Uri with empty queryParameters (= {}) will have a ? at the end even it doens't have any query parameters

Steps to Reproduce

1. Execute flutter run on the code sample (see "Code sample" section below)
2. Notice that the uri finishes with a ? but has no query parameters.

Expected results:

I would expect the uri to be /path

Actual results:

The uri is /path?

void main() {
  final uri = Uri(path: '/path', queryParameters: {});
  print(uri);
}

/path?
