Fix crash with Component.onDestruction
A call to a handler of Component.onDestruction may end up causing WeakValues
such as QQmlData::jsWrapper to be set again, even though they've been set to
undefined in an earlier iteration of the loop that walks through the weak
references. That in turn may result in invalid object references to objects
that are scheduled for destruction by the collector.
So after calling all destroy handlers for QObjects, reset all of the weak
values again.
