Fix the routing issue for /resque/resque

- As Resque is mounted before our username/reponame route,
  /resque/resque goes to mounted resque server and throws error that
  user is not authenticated.
- This commit mounts Resque to /codetriage/resque so /resque/* will work
  fine.
- And we can see our resque-web from /codetriage/resque
