Mac: Fixes a crash in tst_QWidget::updateOnDestroyedSignal
Addendum to change 9b674ddcea7c0ff7912f185474b7d98bc83bd39f.
The problem was that QWidget::paintEngine() (pure virtual) was
called while being in the destructor. The use-case itself
(see above change) is very very corner case, but still,
it shouldn't crash.
