  Fix transactional tracing via LOCAL route

* in local route do not trace as IN msg (on the spot) as logically speaking, there is no IN request here (it is generated by opensips itself)
* trace the OUT request via the TMCB_MSG_SENT_OUT callback, which is now available for the UAC transactions. The tracing must be done AFTER the local route completion, so we can trace the resulting msg (with its changes) and the correct destination (as per local route changes)
