Add warning message when a peer returns a higher slot in their status message

When we connect to a peer, we send a status message containing our latest finalized and head checkpoints. They then respond in a similar way. We should check we are not too far behind them, and log a warning when that happens.

Is this issue still open and pending a fix?
