Two tests (1 failing) showing Collection reset/set should both link related objects

I got bit by this by changing a `foo.fetch()` to `foo.fetch({ reset: true })` in my app, and relations stopped working properly.

Here are two tests that should both have the same behavior, but the "reset" one fails.

FYI I'm using the 'this.set()' in Address#initialize because I don't want fetchRelated() to run, since I know that there's already an ajax request fired to fetch all "countries"
