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

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](https://ember-twiddle.com/5cf56d0b934a05cd450bb77334723c2c?openFiles=routes.three.four.five.path.js%2C&route=%2Fone%2Fnot-two%2Fsome-slug%2Ffour%2Fthe-segment%2Fpath%2Fnew-subpath). The issue seems to either be related to deeply nested routes or `resetNamespace`.
