Route#paramsFor doesn't have proper params for deeply nested routes

[DingoEatingFuzz]

This screenshot summarizes the issue better than words can:

In this scenario, this.paramsFor(this.routeName) returns queryParamsFor, which has the default values for the query params. However, fullQueryParams has the correct values, as backed by queryParams.

I boiled it down to this Ember Twiddle. The issue seems to either be related to deeply nested routes or resetNamespace.
