Changed the identity_map test for belongs_to methods to look at the

target of the association instead of the association itself. The
association doesn't return the object you're looking for, it instead
returns a proxy object. Since this isn't actually an instance of the
class of the association, it will never be the same object as what
you're looking for. if you use #target, however, it gives you access
to the underlying object, which should be the same as one called
straight from the db.
