Describe the bug

Lodestar may print an exception in logs on a discv5 message that does not match its expectations. This is likely just cosmetic

Expected behavior

Lodestar catches the exception and doesn't print a message at INFO level. Maybe this belongs in DEBUG

Steps to reproduce

1. Start a Lodestar mainnet sync
2. Wait - dependent on discv5 received and may be quite rare
