Send vote data only for peers who send us neighbor messages

## Issue summary

- Currently, we gossip prevote/pre-commit messages until the round is done for all connected peers, but it is important that we only send vote data for peers who send us `neighbor messages`
- Would be nice to have a sort of peer view tracker based on neighbor messages received from the network, that way every time we want to send voting data we check in the peer view tracker the peers who are in the same round as us.
