Rename of class with constructor using default arguments causes error

[eric-milles]

Consider the following:

class DefaultParams {
  String value

  DefaultParams(String value = '') {
    this.value = value
  }
  /*@Generated
  DefaultParams() {
    this((String)'')
  }*/
}

Rename "DefaultParams" to anything else and there is a refactoring error due to overlapping edits for generated constructors. The generated constructor(s) for default arguments share the name range of the original for searching purposes.

This may also be an issue for @NamedVariant methods.
