{{link-to}} with only query-params always points to the route in which it was created

[cibernox]

I made an small ember-cli app to reproduce the bug: https://github.com/cibernox/ember-link-to-qps-bug

Steps to reproduce the expected behaviour:

• Go to /cars and paginate. All good
• If you click in the Add new car link to open the child route /cars/create and then exit, the pagination works. All good.

Reproduce the buggy behaviour

1. Go to /cars/create and reload the browser.
2. Close the form. Note that the href in the pagination links is /cars?page=X.
3. Try to paginate. Instead of going to /cars?page=X the app transitions to /cars/create?page=X

Apparently when the {{link-to (query-params page=1)}} is rendered when a sub route is active, the link will "point" to that route even when you transition back to the parent one. That is not the expected behaviour.

I may or may not have time to fix this this week, but i'll try. If anyone knows the exact point where this is failing go ahead and beat me.
