RVI crashes on service invocation with malformed name

[mfeuer]

On master:

python rvi_call.py will_crash

Will trigger a crash in service_edge_rpc.erl:handle_call({ rvi, handle_local_message,...) when authorize_rpc:authorize_local_message() returns not_found instead of [ ok, Signature].

I think Ulf fixed this, but it may have been in another branch than master.
