mon: preserve last_committed_floor across sync

Add a paranoid check to prevent us from forgetting how far ahead our
last_committed was when we sync.  This prevents an i'll-timed forced-sync
from allowing paxos to warp back in time.

This should never happen unless there is a perfect storm of bad admin
decisions and/or bugs, but we guard against it anyway.

See: #5256
