Heretic blade teleportation doesn't work

[SabreML]

(Reported by Fallikaar#5812 on the Discord server.)

Round ID:

N/A

Testmerges:

#469

Reproduction:

1. Become a Heretic.
2. Use a heretic blade (/obj/item/melee/sickly_blade) in your hand, which should teleport you to a safe location.
3. Remain in the same spot, now without a blade.

This is being caused by the is_safe_turf() proc not being fully updated for ZAS yet, and is presumably affecting other things that use the proc as well.
Everything up to line 151 seems to work fine, but after that point the code is assuming that floor_gases is a /datum/gas_mixture rather than a list.

I believe I fixed this a while ago and just forgot to mark the issue. If it persists, please inform me.
