Should have the delegate modify the list, both by adding and removing a proxy
(Different tests), and make sure neither has an effect on future resolve proxy
requests.

Wrote a test, but it seems vaguely odd to me: it's mostly (though not entirely)
testing the behavior of my mock network delegate implementation.
