fix(rtable): Prevent direct send hairpins

If the current node is listed as an endpoint for a message type
that this process would add to the route table a hair-pin loop
back to the node can happen. This isn't desireable and this
change will prevent the current node from being added as a
recipient endpoint to any route table entry.
