Router Service transitionTo breaks with Query Params on nested transition

Calling `transitionTo` on a service in the context of an existing transition causes an assertion error to be thrown.

Example Twiddle [here](https://ember-twiddle.com/3e2ad44eeada3e36c72ddd2f9548712e?openFiles=services.auth.js%2C)

Minimal logic from the reproduction above is: index route's `beforeModel` calls the auth service's `ensureSignedIn` method which uses the router's `transitionTo` method and includes a query param.

Calling it results in:
```
Assertion Failed: You passed the `login:security_key` query parameter during a transition into login, please update to security_key
```
