Issue Addressed
This PR fixes an intermittently failing test:
https://github.com/sigp/lighthouse/actions/runs/12246911324/job/34163756917
It fails when the validator subnets happens to be in the permanent subscriptions - the existing check doesn't actually handle this correctly as
subnet_service.is_subscribed
checks for short-lived subscription. In the case where the subnet is already subscribed as a permanent subscription, there will be no new subscription events.
