Removed JobIncompleteError

We have a scheduled task to check that all the jobs have completed, this will catch if an app is shut down and the job is complete yet, we only wait 10 seconds before forcing the app to shut down.
The task was raising a JobIncompleteError, yet it's not an error the task is performing it's task correctly and calling the appropriate task to restart the job.
Also used apply_sync to create the task instead of send_task.
