fish will print messages for some jobs when they exit abnormally, such as with SIGABRT. If a job exits abnormally inside the prompt, then (prior to this commit) fish would print the message and re-trigger the prompt, which could result in an infinite loop. This has existed for a very long time. Fix it by reaping jobs after running the prompt, and NOT triggering a redraw based on that reaping. We still print the message but the prompt is not executed. Add a test. Fixes #9796
