Pass owner instead of registry to ember-data's setupContainer

The `setupContainer` function of `ember-data` expects an application
instance to be passed - in this case that is the faked owner object that
we create when using a custom resolver in tests.

This behaviour previously worked because `ember-data` supported the
usage of legacy function `optionsForType` which exists on the `registry`
object. However, they removed that legacy fallback in v4 and replaced it
with `registerOptionsForType` which does not exist on the registry but
only on the owner.
