Purpose of change

Fixes #3754

Describe the solution

Forges were trying to consume charges of the fake forge item itself (e.g. char_forge) instead of its ammo (e.g. charcoal).

Additional context

I'm not sure if this does relate to #5439. If someone could check if it's still present that would be great but I'm guessing it will be.

Also notice there's a very similar thing just above this (line 5099) for the power grid charge consumption. Again it's using the fake item as what it's depleting but I'm not sure if that's correct for power? Could you take a quick look @chaosvolt and make sure it's ok?

1. spawned in rock kiln and charged it with 100 charcoals.
2. crafted 1 clay jug which uses 80 kiln charges.
3. confirmed only 20 charges left.

I'm not sure if this does relate to #5439.

i'm unable to reproduce this, maybe could ask @RoyalFox2140 who could reproduce it. (but how, like we both are using linux)

it seems to use grid charge correctly atm.
