We shouldn't log nodes by nickname
Node nicknames are not unique, and not what people should be entering into their configurations. When we have any log messages that describes a node by its nickname alone, that's a problem. Instead, we should probably log something more like the node ID or the "extended node ID" format ($hexid~nickname), and maybe the node IP:ORPort too.
As we do this, we should also be careful about logging bridge addresses or node IDs.
