sleep before updating and deleting test documents - otherwise their index entries may not be fully written and this causes errors (update and delete first attempt to remove index references, but if they are not in the DB yet then they are not removed but then they do get added and the FK constraints make the delete fail). Since we know indexing occurs in a separate thread with a configured delay, we just use this same delay in our testing.
