[Serusers] Ser backup route

[Jiri Kuthan]

see for example append_branch in http://www.iptel.org/ser/doc/seruser/seruser.html#REPLYPROCESSING

t_relay "exhausts" all active branches. next call of t_relay
from failure_route has no "unused" branch and it completes
without doing any work. You need to append a new branch.
