New specs for :through associations

The associations on already saved models currently pass.  However, the
associations on unsaved (i.e. in-memory) models do not currently pass.
During a discussion today on #dm-hacking, ssmoot, dkubb, and I agree
that supporting in-memory associations makes sense.
