Create job-exit caller events inside event handlers

Browse Source 
f7e2e7d26b forbid any job exit events
from happening inside jobs that were themselves event handlers, but
that causes e.g.

```fish
function f --on-event fish_prompt
source (echo "echo hello world" | psub)
end
```

to not trigger psub's cleanup, so it leaves files in $TMPDIR behind.

This was hit by pyenv, because that still uses `source (thing |
psub)`.

Fixes #7792.
