  mid_registrar: Remove Path when forwarding REGISTERs

Regardless of its working mode, the mid-registrar always rewrites the
Contact header to point to itself, so it stays in the path of future
calls.  Consequently, when relaying REGISTERs, it MUST no longer include
the Path header(s) built by the upstream elements, as this will break
call routing.
