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. Reviewed-by: bnilsen
