Accessibility: Fix crash when updating in dtor
This happens for example when running several tests.
Widgets in destructor should be treated as invalid
since their window pointer and other properties are
no longer valid.
When deleting a window containing only a table view
there would be a table model reset update comming from
the window being destroyed.
