e46cc30b-13ca-4778-b856-e84b0677493d@group-059247EC8137-FOLLOWER: reject 
PRE_VOTE from c7e3fa47-df62-4883-8d6e-50c3b6a9b94c: this server is a follower 
and still has a valid leader c7e3fa47-df62-4883-8d6e-50c3b6a9b94c
{code}
We can add another check so that if the candidate has the same peer ID as the 
follower's current recognized leader, we approve the PRE_VOTE request.
