a11y: Do not refer to destructed QObject in Windows bridge
The crash could happen if a QWidget in the UI got deleted, and
the AT client later tried to access the widget through the cache
(qAccessibleRecentSentEvents()).
Solution: Use a QPointer as a guard.
Task-number: QTBUG-26187
Change-Id: I41eab158989fddfa147309b6bd91ac0cd1fe7b1a
