This synchronizes the logic we have between what peers we allow to connect to us and what think are connecting to us.
Specifically, peers that have a history of connecting to us via an IP address that is currently banned (i.e has a number of peers currently banned associated with this IP) we prevent their connection, even if they are connecting on a new IP address.
This should resolve some potential error logs also.
