fix bootstrap: add node after successful handshake

Browse Source 
Previous version was very conservative about adding nodes to the
routing table, requiring a full request/response message exchange
initiated by us.
Here we also add the node as 'seen' if the whoareyou/handshake
exchange was successful.
This significantly speeds up bootstreap from 0
