Add dependency for parent_pre post updates to parent deletes

Fixed issue in post_update feature where an UPDATE is emitted
when the parent object has been deleted but the dependent object
is not.   This issue has existed for a long time however
since 1.2 now asserts rows matched for post_update, this
was raising an error.
