Ivan Kozlovic 77aead807c Send LS- without origin to route ...

When cluster origin code was added, a server may send LS+ with
an origin cluster name in the protocol. Parsing code from a ROUTER
connection was adjusted to understand this LS+ protocol.
However, the server was also sending an LS- with origin but the
parsing code was not able to understand that. When the unsub was
for a queue subscription, this would cause the parser to error out
and close the route connection.

This PR sends an LS- without the origin in this case (so that tracing
makes sense in term of LS+/LS- sent to a route). The receiving side
then traces appropriate LS- but processes as a normal RS-.

Resolves #1751
