After upgrading ember to 1.8.1 tests pass, but I found a few cases where
things break (for example when navigating between certain routes). I'm
reverting for now.
This reverts commit fa5e9179af, reversing
changes made to 978c887123.
* Add `travis.source_endpoint` meta (fixes many tests with hard
expectations on `http://github.com` being in URL paths).
* Wrap `Ember.run.once` in a `Ember.run` (prevents test auto-run
assertion).
* Fix expect counts for a couple tests.
