ensure with poly entities are also reconstituted for GC'ed AC
Fixed regression in ORM regarding an internal reconstitution step for the
func:`_orm.with_polymorphic` construct, when the user-facing object is
garbage collected as the query is processed. The reconstitution was not
ensuring the sub-entities for the "polymorphic" case were handled, leading
to an ``AttributeError``.
Fixes: #6680
