tmx(k): mi_tm_uac_dlg uris fix

Replaced dlg.hooks.request_uri  with dlg.rem_uri and
dlg.hooks.next_hop with dlg.rem_target.
[ In sr tm the dialog hooks should not be changed, they are only
used for internal caching. Any change to the hooks will be lost
immediately after t_uac() is called (t_uac() re-calculates the
hooks each time it is called). One should use instead the
correspondent dlg structure members. ]
