Fix URN parsing

1. Add expectations to tests, they didn't work properly because we have closures, so we didn't see some of them actually weren't passing.
2. Back to the condition we had before Fix URL or URI condition logic #20, prefix couldn't have query as a prefix, because prefix is a part of the route, so it's a part of the query as well.
3. Fix guard condition for URL parsing.

@zenangst I'm gonna merge it because this thingy is kinda blocking me at the moment 😄 Just write if you don't agree with something here.
