[Bugfix] Container.options populate options

As has been highlighted here: https://github.com/emberjs/ember.js/issues/9371 by @stefanpenner Container.options was actually populating the _typeOptions object.

I assume that Container.options should set the options for a given factory specified by its full name, so the fix and the test apply/verify that logic: The test would fail without the fix because by default the `singleton` option is `true`, so both `postView`'s would be identical if we were not able to set options for that factory.
