Fix crash related to deleted items being processed

If an item from the media store was being edited
there is a race condition where the item may be
deleted from the media store before it is finished

The resulting update to the media store cannot 
find the original item, and therefore results in
0 rows being updated, which is what is desired,
as the item was deleted by the user.
