Summary: Dialog topology_hiding does not restore RR for prov replies

Initial Comment:
After calling topology_hiding(), provisional responses (183,180) passed through the proxy do not include the Record-Route header. This is problematic for PRACK support, as clients will send these directly to the proxy doing topology_hiding and bypass any other proxies in the chain.

On another note, these replies also went through another opensips proxy (which had done a record_route, no topology_hiding) and it did not fix-up the provisional replies either. Would it make sense to have opensips check and fix the record-route headers on replies for the case of buggy clients?

I can provide captures for the examples of the missing record-route header on provisional responses if needed.
