Hub IPs are leaking to leafnodes even if no_advertise is set to true

[formzeke]

Observed behavior

Leaf nodes get the hub IP (the node that they are connected to) when no_advertise is set to true on direct connection. If the connection is broken, they will use this list to reconnect (and fail).

Expected behavior

if no_advertise is set, no hub IP is leaking in any path.
Currently the workaround is to set the "leafnodes" { "advertise": "" } to override behaviour.
