With multi-relay, it can happen that one of the relays can't connect or is stuck in "Connecting...". In this case, right now we show "Not Connected"/"Connecting" as the connectivity, which multiple users already complained about, esp. since it's not obvious how to remove an unpublished, not working relay.

Instead, the new logic is:
- If any relay is working, then we signal this to the user, to signal that new messages may come in.
- Only show "Connecting..." or "Not Connected" if all of the relays are failing to connect, because if any of the relays can connect then things are mostly fine.
