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.
* don't use __container__
* register it as a factory on container and inject into routes and
controller
* avoid afterSignIn errors by checking on hooksTarget, ApplicationRoute
should register itself as a hooksTarget
* keep user info on auth
