> Currently when the active transitions to standby (eg for a manual failover)
> the EditLogTailer starts tailing edits at the wrong transaction ID. This
> causes it to double-apply a bunch of edits, which causes various problems. We
> need to add a test which checks this state transition and fix any related
> bugs.
