[FEATURE query-params-new] Normalize full name before trying to check in cache (fixes #4420).

We need to use a normalized version of `fullName` otherwise it will
return always the prototype.

The reason is that that keys are always normalized on the cache, we
end up querying for keys like 'controller:post.index' when it is stored
as 'controller.postsIndex'.
