This was a little tricky to get right. The "spin the event loop" bit is weird but doing a setTimout to call resolve is already redundant since resolve calls the promise callbacks on the next turn of the event loop anyway. Basically, the test just needed to move more stuff to the content process. MozReview-Commit-ID: KrZZU5reJf7
