[MIRROR] Cryo tubes will dump legions spawned inside them when opened (…

…#809)

* Cryo tubes will dump legions spawned inside them when opened (#81273)

## About The Pull Request

Someone reported this on discord and didn't make an issue report, gross
Anyway if you get turned into a legion via legion cancer it spawns in
your loc, if your loc is a cryo tube then it only dumps specifically the
person who was placed into the tube rather than all mobs when opened, so
it resulted in a tube which would endlessly spawn legion skulls until
destroyed.

I fixed this by making cryo tubes dump all mobs regardless of how they
are placed into the tube.
I don't think there were _likely_ to be other related edge cases because
xeno larvae use turf instead of loc when created, but I think spawning
in loc is more fun so I fixed that rather than just making it spawn in
the turf.

## Changelog

:cl:
fix: Being consumed by the flesh of the necropolis while inside a cryo
tube will no longer convert the tube into a legion spawn point until the
tube is destroyed
