Fixes a crash when unregistering a recognizer.
Another fix for the same problem - we also need to be careful - when ungrabbing
a gesture for the recognizer that has already been destroyed and cleaning up
the QGesture object for it we need to make sure we know it is removed from the
obsolete gestures list so that we won't delete it again in the QGestureManager
detructor.
Task-number: QTBUG-9801
