Skip type normalization

Since we cannot [normalize a standalone type](https://github.com/emberjs/ember.js/blob/master/packages/ember-application/lib/system/resolver.js#L95), type injections are not normalized. However types are being normalized on registration.  This causes a mismatch between the type for injection and the registered type.

For example: `container.register('dataAdapter:main')` gets registered as `data-adapter:main`, but `container.injection('dataAdapter', 'store', 'store:main')` injects into `dataAdapter` and not `data-adapter`.
