bug: can't start node without subscribed pubsub topics in clusterIds different than 0

[gabrielmer]

Problem

Currently, we are allowed to start a node on clusterId 0 without subscribing to pubsub topics from startup, but not for clusterIds different than 0. In that case, we get the following error:

ERR 2023-12-20 11:01:10.765+01:00 no sharding info                           topics="wakunode main" tid=93403 file=app.nim:138

To reproduce

1. Run ./build/wakunode2 --relay=true --cluster-id=18

Expected behavior

We should be able to start nodes in clusterIds different than 0 without having to subscribe to pubsub topics from the CLI.
