rocket: User sign up guard forwards over failures When no user can be found, the User implementation of FromRequest was failing, which is a mistake. This meant that no other routes were tried and thus assigning policies to routes failed. This changes fixes that by forwarding instead. To be frank, this is over forwarding, and can still be improved on.
