Fix hard del/race condition in reflections (#93328)

## About The Pull Request

Tin, the proc that's managing references should remove the thing from
the list before calling qdel on it. Also, it should not be calling qdel
on something that's already being qdeleted (which could happen before if
`nuke_reflection()` was reached via the `COMSIG_QDELING` signal).
