uac: Fix From/To header restore with dialog store
When replacing From/To header and using dialog module to store original URIs (modparam restore_dlg=1), restoring of headers does not work for replies to in-dialog requests sent upstream. Add in-dialog request's direction to TM callback parameter, so correct URIs are restored for replies to upstream in-dialog requests.
