Ember no longer defers to ember-cli's resolver

[bcardarella]

Since e5148e6 the decoupling of the Registry from the Container broke the API for deferring to ember-cli's Resolver.

Specifically, resolveOther is no longer being called for ember-resolver. This broke ember-validations as it is relying upon resolving outside of the application's namespace: https://github.com/dockyard/ember-validations/blob/master/addon/mixin.js#L55-L56 which is a feature supported by ember-resolve since 0.1.8 (Oct '14)

I believe this should be treated as a bug and patched rather than backporting ember-resolver's support into the Registry.

False alarm, I was not building my container properly in the test suite.
