Don't crash in wxControl::GetLabel when getting the label

fails (perhaps because the widget is not realized?).
  Correct wxRTTI information for wxFrame: it derives from
wxTopLevelWindow, not wxWindow.
  Don't try setting Widget size to 0, because it will fail: set
it to 1 instead which is exactly as sensible, but does not crash.
