> Handle race condition between compaction txn abort/commit and heartbeater

> This issue is the following: once the compaction worker finishes,
> commitTxn/abortTxn is invoked first, and the heartbeater thread is only
> interrupted after that. This can lead to race conditions where the txn has
> already been deleted from the backend DB via commit/abort, but the
> concurrently running heartbeater thread still attempts to send a last
> heartbeat after that, but the txn id won't be found in the DB, leading to
> {{{}NoSuchTxnException{}}}.
