Yes, if the r-uri is changed in failure route, a new branch is created 
by t_relay() without need of using explicitly append_branch().

But again, using append_branch() once before t_relay() there should do 
nothing (backward compatible behavior). Unless some new code changed 
that behavior -- iirc, append_branch() was affected by some outbound code.
