fix(has-many): detect removed children by object id lookup

The `array_udiff()` comparator returned only 0 or -1, so the sort-based diff reported children that stayed in the collection as removed, and a nullable relation nulled their foreign keys. A lookup by `spl_object_id()` needs no ordering contract and runs in linear time. Fixes #575.
