Fix type inferencing of overloaded methods and property expression argument(s)

[eric-milles]

Consider the following:

interface Face {
  setValue(String key, int val)
  setValue(String key, long val)
  setValue(String key, double val)
  setValue(String key, boolean val)
}

interface Keys {
  String ONE = 'one'
  String TWO = 'two'
}

void test(Face face) {
  face.with {
    setValue(Keys.ONE, false)
  }
}

Code hover (F2) should display "setValue(String,boolean)" for "setValue(Keys.ONE, false)".
Currently the first setter overload is chosen because the property expression is mapped to the type Object when choosing between overloads.
