Try to tidy up a bit, move checks for if we are already calling/connected 
Something I noticed when working on reconfigure support for the "Listen"
option is that we have some rather huge weaknesses in our multicasting
design. Right now if we change our Listen address, it's not really
possible for remote nodes to know whether they are still connected to
us, so they start connecting in response to our changed beacons. They
can't know that they already know about us until *after* the handshake
but this registers in the local client log as repeated Connect/Disconnects
even though the existing peerings never actually drop.
