Roxy 7f808bcec6 Fix flaky hard delete related to wound-induced brain traumas (#90751)
## About The Pull Request

Brain traumas caused by head wounds are stored as a reference on the
wound, but certain brain traumas (like split personality) `qdel`
themselves in `on_gain()` if conditions aren't valid for them to exist,
`/obj/item/organ/brain/proc/brain_gain_trauma` returns a reference even
if this happens, leading to the ref being stored on the wound and
preventing the trauma from being fully deleted.

## Why It's Good For The Game

Fixes #87752 

## Changelog
