HTTP API: Don't loop redirecting when URL wasn't found

HTTP API: Don't loop redirecting when URL wasn't found

Currently when api version isn't provided in URL then request is
redirected to default one. If requested resource isn't found there then
the redirected will be served by the same handler, so it will be
redirected which results in another redirection and so on. This change
introduces new handler that responds with 404 error when page wasn't
found in default version of API.
