[ASTERIXDB-2301][TX] Fix Abort of DELETE operation

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
- Fix the undo logic of the DELETE operation. Previously undo
of DELETE is implemented as re-inserting the old value. However,
if the deleted record is from the disk component, the old value could be
null. In this case, we simply need to physically deleted the anti-matter
key from the memory component, exactly the same as undo upsert.
- Add test cases for undo.
