Fix additional cryo reagent duplication via TOUCH reaction

[Drulikar]

About the pull request

This PR is a follow up to #6058 where it was brought to my attention that chemicals were still duplicating from cryotube beakers. This is because the cryotube was trying to simulate the patient being immersed in the reagents, but with a 50% permeability that doesn't even consume the reacted reagents, it easily gets out of control if large volumes are involved and or the ratio of cryo meds is small in the mixture causing frequent reapplications of reagents.

Explain why it's good for the game

It was intended to remove chemical duplication via cyropods. This shores up another source of chemical duplication.

if the issue is the duplication of reagents, couldn't this be disabled in reaction() instead to maintain per-chemical touch interactions?

If the reaction is touch, and user has no biosuit, 50% is duplicated into the mob. The reaction itself probably should change such that whatever enters the mob is deleted from holder, but I have no idea the implications what all that may do; it also just makes rationing what is applied to the mob difficult.

Let me know if you prefer that.
