Improve the handling of sync child jobs to ensure it behaves correctly in all scenarios. The sync service now uses a isolated context to avoid all the pipeline stages shutting down before all the sync tasks have had the opportunity to run their course. The job waiter now immediately starts with a counter of 1 and waits until all the child and the parent job finish before considering the work to be finished. Finally, we also handle the case where a sync job can't be queued because the calling context has been cancelled.
