 chutney does some weird things with TestingV3AuthVotingStartOffset that
 might cause this issue. Occasionally one authority starts before the
 offset, and another starts after it, and their consensuses get out of
 sync.

 But this is really weird: it is an authority rejecting its own vote, so it
 has to have the same clock, right?
