Issue Type: Bug

1. Create a new js file, with following content:

var a = require('./a');
function f() {
	a;
}

2. Select declaration of f, hit ⌘ + ., and select "Move to a new file".

Expected behavior:
A new file with declaration of f is created, and declaration of a is left unchanged.

Actual behavior:
A new file with declaration of f is created, but declaration of a becomes:

var = require('./a');
