Updated qwidget winId auto-tests
1. Added a new test step, winIdChangeEvent, to test that QWidget::setWinId correctly sends WinIdChange events. 2. The persistentWinId test step check the following assertion: re-parenting a native widget causes its own winId to change, but not those of its (native) descendents. This assertion is not true for Symbian, so this test step has been replaced, on Symbian, by reparentCausesChildWinIdChange, which checks the inverse assumption, i.e. that the native descendents' winIds also change.
