Give the ember tests some idiomatic love..

- Utilize ember's run-loop as it was meant to be utilized.
- Use minified ember build, as this is closer to production.

Please  note, this is a quite unnatural test. Forcing typically temporally distinct operations (such as user clicks) to be synchronous, grinds against some frameworks architecture. I do not believe these tests are trying explicitly to mis-represent, but
I fear this approach is flawed. This commit allows ember's run-loop to do what it was
Intended todo, which helps dramatically. 

I would love to find a more natural method of testing these types of scenarios.
