Make deleting with optimistic locking respect NULL
For now deleting with optimistic locking is broken when
lock_version is still NULL, because Rails would try to
delete with lock_version = 0 while in the database
the column is still NULL.
The monkey patches would force Rails just pass whatever
in the column, and stop Rails from casting NULL into 0
when the value is read from database.
