Widgets: Deactivate effect on destruction

Browse Source 
If a QGraphicsEffect is active during destruction, the corresponding
widget does not inform it's parent about this change which leads to
artefacts of the old effect. Therefore trigger an update through
effectBoundingRectChanged() if the graphics effect source changes.

Fixes: QTBUG-109165
Pick-to: 6.5 6.4
