Fix race condition in drag and drop6.7
The data source may be deleted by libwayland while we hold a
reference to it. This could cause crashes when dragging
and dropping repeatedly and very rapidly between two
components.
Tapping into sourceDestroyed() for this as well allows us to
recover more gracefully.
This also required adding some null pointer checks to the code,
since it wasn't really prepared for the data source
disappearing.

Fixes: QTBUG-124502
