Canceling a job can give wrong error message for related project sync

Please confirm the following

• I agree to follow this project's code of conduct.
• I have checked the current issues for duplicates.
• I understand that AWX is open source software provided for free and that I might not receive a timely response.

Bug Summary

The propagation of the cancellation signals is not working 100% as intended.

If you launch a job on a cluster that needs to run a project sync in advance to sync the source tree, and you cancel the job in the right time window, the project update will give an error status with the message:

Task was canceled due to receiving a shutdown signal.

We don't want this, we want a plain "canceled" status instead (or in the absence of that, an appropriate message).

Steps to reproduce

Launch a job on a cluster, so that it's likely that it will trigger a project sync before-hand to update the source tree on the node it runs on.

Quickly cancel the job.

Expected results

Job will get canceled status.

Actual results

Job gets this status

This is because the project update error followed through the fail chain. Click on the project link in that page:

So that's the bug there.

Additional information

This was triggered indirectly via a workflow as well.

>>> job = Job.objects.get(pk=4635)
>>> job.cancel_flag
True
>>> job.project_update
<ProjectUpdate: 2022-09-02 18:39:18.450958+00:00-4636-failed>
>>> job.project_update.cancel_flag
False

Is the data determined from the scenario given above. The bug is that the project update should probably have had the cancel_flag flipped.

this is probably fallout from #12435

[AlanCoding]

I was wrong, and it turns out this bug only happened when running with the branch #11745

I've pushed a fix, and will close this issue.
