fix: Fix UsedItem being called twice

[Someone-193]

Description

Describe the changes
I feel kinda dumb for not checking but honestly this fix was really annoying to research. NW should really refactor their old code, they could probably get more functionality + features for modders if they did so.

What is the current behavior? (You can also link to an open issue here)
see title

What is the new behavior? (if this is a feature change)
its not called twice, nor should it be possible

Does this PR introduce a breaking change? (What changes might users need to make in their application due to this PR?)

Other information:
I think I've handled every sane edge case but if there's any bug in my patch, players can be disconnected just for holstering a consumable so tread carefully when reviewing this.
