IPCS not working since 1.6.X ? #968
Description
Describe the bug
avalanchego does not send any data on the ipcs unix sockets
To Reproduce
run
./avalanchego --http-host 0.0.0.0 --api-ipcs-enabled=true --network-id=1 --api-admin-enabled=false --api-keystore-enabled=false --ipcs-chain-ids=2oYMBNV4eNHyqk2fjjV5nVQLDbtmNJzq5s3qs3Lo6ftnC6FByM
connect a client to it :
nc -U /tmp/1-2oYMBNV4eNHyqk2fjjV5nVQLDbtmNJzq5s3qs3Lo6ftnC6FByM-consensus
no data are spitted out
Expected behavior
getting ipcs message defined in https://docs.avax.network/build/avalanchego-apis/ipc-api#ipc-message-format
Operating System
cat /etc/lsb-release

Additional context
for debugging purpose i started the node with :
strace -f -e trace=process,socketpair,open,close,dup,dup2,read,write,connect -o /tmp/c.log ./avalanchego --log-dir /home/avax/mainnet/logs --db-dir /home/avax/mainnet/gecko/ --http-host 0.0.0.0 --api-ipcs-enabled=true --network-id=1 --api-admin-enabled=false --api-keystore-enabled=false --ipcs-chain-ids=2oYMBNV4eNHyqk2fjjV5nVQLDbtmNJzq5s3qs3Lo6ftnC6FByM
waited it bootstrap completely; issued ipcs.unpublishBlockchain and ipcs.publishBlockchain yet i can't see any activity on the unix socket ...
