If the mon failover is in progress, ensure the removal of an extra mon deployment is skipped since that code path only has one mon in the list for the mon that was just newly started. The extra mon was erroneously removing a random mon in that case, followed immediately by the mon failover completing and removing the expected failed mon, and potentially causing mon quroum loss.
This is a regression from #14667, which was included in v1.15.2.
