[Bugfix] Container.options populate options

As has been highlighted here: https://github.com/emberjs/ember.js/issues/9371 Container.options was actually populating the _optionsForType object.

I assume that Container.options should only set the options for a given factory specified by its full name, rather than by type, so the code and the test apply/verify that logic.
