confirmOnQuit causes brief hang on clean tree

[xkcd386at]

Describe the bug

Setting confirmOnQuit: true causes lazygit to briefly hang, then put out a message saying "cannot kill child process" before exiting.

This does not happen if the repo has any modified files. Only when the repo is "clean".

To Reproduce

Steps to reproduce the behavior:

1. Install version 0.64 (latest)
2. add confirmOnQuit: true to config.yml
3. open a clean repo
4. type "q", hit "Enter" to confirm
5. lazygit will pause a second or two, then print "cannot kill child process" before exiting

Expected behavior

No pause or spurious error message in step 5.

Thanks for the report; this is a regression in 0.64.0, it worked before. Here's a fix: #5919.

"A second or two" is not quite accurate, it should be exactly 3 seconds. And what's funny: we even have a test for this exact scenario, but it didn't fail with 0.64.0, it just started to take 3.1 seconds instead of 0.1s; nobody noticed this.
