Fixes CursorChange and TooltipChange events delivery for QGraphicsWidget
As the documentation mentions, these two events are delivered respectively after the cursor has changed and after the tooltip has changed. These two events were previously delivered just before. This patch is needed for fixing QTBUG-5349 even if it is not directly related. Auto-test included. Reviewed-by: bnilsen
