Traceback when unable to resume after CTRL-C

Bug Description

I came back to a test that was sitting at the review screen (where you can pick failed / skipped tests to re-run) and hit F to finish. I realized I needed to do something else, so I hit CTRL-C and restarted using the test-memory launcher from the server provider.

However, now, every attempt fails with a traceback as outlined in the log output below.

My initial guess on this is that because I Hit F it had already started marking things as non-resumable and crafting the submission file, and that makes it "resume not-supported"

So this is probably more about cleaning up or handling that exception to be more user friendly / informative.

Workaround to unstick this was to delete the session data in /var/tmp.

To Reproduce

Ran test-memory until end of run On the review screen I hit F to finish but then quicly hit CTRL-C to cancel out completely Restarted test-memory Get traceback.

Environment

Checkbox v 4.0.0.dev292 from edge PPA Noble on Z13 LPAR instance
