Vadim Zeitlin 602b4a6863 Run all wxTextEntry unit tests for wxTextCtrl too 
Comment stated that InsertionPoint() didn't pass, but it was actually
already running (and passing) and the only excluded test was the
TextChangeEvents() one which really should pass for multiline controls
as well, so run it too.
