QNotifiedProperty: avoid crash
We can end up in a situation where a (soon to be destroyed) observer is
owned by a binding which is about to be deleted. If in that situation
the binding is destroyed first, we end up with a dangling pointer
and ensuing memory corruption. Instead, we now first transfer the
ownership of the observer and only destroy the binding afterwards.
