We have a bug that results in sending unneeded ajax queries on missing
log parts. I'm working on a fix, but it may take a while, because I want
to refactor a few parts of the app instead of putting more hacks on
legacy code. To help with the situation I'm increasing timeout for
pusher fallback.
* 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.
