[SR-Users] 401 responses ending up in onreply_route instead of failure_route

Are you sure there is no other set for failure route before getting to
route[RELAY]? Inside it, there is an IF for setting the failure route.
If not set in other place, I can check the code once I get a chance, but
I don't remember any filtering out 401. Maybe you can give a quick try
without dialog event route to see if there is any relation.
Cheers,
Daniel
