Add a failing test for query params cache with resetNamespace

[wagenet]

The basic issue here is that the cache key calculator uses the current route name to determine the prefix for the key which enables a correct value lookup. However, if you use resetNamespace the prefix won't match and it calculates the prefix incorrectly. In this example, it will try get the value from parent.child.child_id (IIRC) and instead of that getting the value of child_id from the parent.child route, it will try to get the value of child.child_id from the parent route.

@wagenet is this still relevant?

@locks I just rebased. Looks like CI still fails.
