This also cleans up the addrman (de)serialization code paths to only allow `Disk` serialization. Some unit tests previously forced a `Network` serialization, which does not make sense, because Bitcoin Core in production will always `Disk` serialize. This cleanup idea was suggested by Pieter Wuille and implemented by Anthony Towns. Co-authored-by: Pieter Wuille <pieter@wuille.net> Co-authored-by: Anthony Towns <aj@erisian.com.au>
