Fix rename of accessor method to non-accessor name

[eric-milles]

Consider the following:

class Foo {
  def getBar() {} // rename to "readBar"
  void setBar(value) {} // rename to "writeBar"
}

new Foo().with {
  def x = bar // "bar" should be replaced by "readBar()"
  bar = x // "bar = x" should be replaced by "writeBar(x)"
}

If "getBar" is renamed to a non-accessor style name line "readBar" the property access is not properly refactored to "readBar()".
