'change' event firing when shouldn't (regression)

This test fails on `master`, but passes back on b1abe380dacf7c541dd58b97924e624c104ffc6c

Let me know if you need more context / want to know why I'm trying to do what I am.

In summary: the Contact objects contain nested json data. When fetching the parent Company I don't want any Contacts to re-render if their data (phones #s) haven't changed. So I set a fake ID in parse so backbone-relational could properly keep track of the objects via the Store. In master, a change event gets fired on Contact regardless.

Ideas?
