Problem
When users delete a BatchExport we also delete the underlying Temporal Schedule. However, we do not cancel any running backfill Workflows that may be trying to backfill the Schedule we just deleted. This leaves the Workflows hanging around waiting forever for a Schedule that doesn't exist 💔
Changes
BatchExport
, also cancel any runningBatchExportBackfill
