Avoid writing to config file while quitting

Refs #17060

/cc @Arcanemagus - I was never able to reproduce the config loss using your steps. It seems like it might be more unlikely on macOs, or depending on the speed of your disk. I'm going to go ahead speculatively merge this PR that I think might fix the problem. When you get a chance, would you mind trying to reproduce the bug with a new build?

Apparently reproducing #17060 is a lot more difficult on compiled builds than I remember. It takes ~4 restarts to reproduce on Atom v1.27.0-beta0, but ~40 on a build based on the same commit 😮.

In any case I did manage to reproduce it on a build based on the commit right before this merged, and I so far haven't been able to reproduce on a build after this was merged so I think we can call this one mitigated. 🎉

Nice work!

It seems I spoke too soon, opened up that profile/build again to check something else and the settings were wiped. I'm wondering if a very rare bug I was seeing during testing might actually be related. Trying to find better reproduction steps.

This has happened to me as well, using only the love2d ide packages.

It's a huge pain, but I've become great at setting up atom again, and again, and again.
