We complete the actions in the database. However, we don't delete
the batch processes. Woo thinks those crashed. It tries to log an

Action Scheduler uses WP Cron as trigger.
When it is initially locked it takes more time for Action Scheduler to start
and some tests that rely on background job fail with timeout.
