Fix broken test that magically started failing.
Fix broken test that magically started failing.

The only thing that's changed since these tests last passed (as proven
by Travis) is either Go 1.4 or some update to a dependency (like
Testify). I had Travis run it in 1.3 and it still failed, so I guess
Testify's behavior changed, or I'm insane.
