Recurring automations are triggered by a scheduled job that runs every minute and checks for due automations, runs them and then marks as them as completed (by deleting the
PendingAutomationrecord). However, the job is currently subject to a race condition where a recurring automation can be executed more than once at its due date if it takes more than a minute to finish.This PR adds a mutex around the code that triggers the recurring automation so that no concurrent executions can happen for a single automation.
