Adjusting to ember-simple-auth 0.1.3 setup: passing container as param

Since v0.1.3 simplabs/ember-simple-auth@79437455c86760a60a8b4825acdc40b227395e13  Ember.SimpleAuth.setup expects both container and application to be passed as parameters. If not passed, `container` (which points to the passed application parameter) fails to resolve the `injection` function and setup breaks.
