Nathan Singer 6d3008f8e9 Fixes getting negative moodlet from fire while immune (#86583) 
Also doesn't commit this to the mobs memory, as why would this be a
memorable moment when it doesn't affect you
## About The Pull Request

Closes https://github.com/tgstation/tgstation/issues/85105
## Why It's Good For The Game

if being on fire doesn't affect you why should you be upset over it
## Changelog
🆑
