Test instance for matching class hierarchy on get_from_identity
Fixed issue where a lazyload that uses session-local "get" against a target
many-to-one relationship where an object with the correct primary key is
present, however it's an instance of a sibling class, does not correctly
return None as is the case when the lazy loader actually emits a load for
that row.
Fixes: #5210
