There is no point in actually notifying the AT client that the object got destroyed,
because the AT client won't query for get_accChild if the event is ObjectDestroyed
anyway, and we have no other way of mapping the eventId argument to the actual
child/descendant object. (Firefox seems to simply completely ignore
EVENT_OBJECT_DESTROY).
We therefore guard each QObject in the cache with a QPointer, and only notify the AT
client if the type is not ObjectDestroyed.
