I attached logs of a run of sharding/auth.js that demonstrates this problem.
The test fails after triggering this invariant:

The problem seems to be that a new primary is elected, then the previous primary gets a heartbeat response from it. The heartbeat response tells it to step itself down, and also includes a new term, so we now call _stepDownStart() twice, which schedules two different stepdown tasks, causing the second one to signal the already-signaled _stepDownFinishEvent
