Magiclym: Negative Foods, able to eat forever

### Describe the bug

Turns out that if you have glowing mushrooms from the Magiclym mod, and use them in an auto eat zone, you can constantly eat them until their stacks becomes negative.

DEBUG : did not found item glowing mushroom caps to remove it!

FUNCTION : i_rem
FILE : D:\a\Cataclysm-DDA\Cataclysm-DDA\src\character_inventory.cpp
LINE : 289
VERSION : 3d15dcc

Once this happens, the mushroom stack have gone into the negatives, and you can keep eating from the stack forever if you want. However, if you attempt to pick up the stack, or move the stack, you cause a stack overflow and crash the game.

### Attach save file

### Steps to reproduce

1. Press (R)ead
2. Read while auto eating, wait until you start eating glowing mushrooms (Likely a few IRL seconds)
3. Resume reading until auto eating mushrooms.
4. Voila, error!

### Expected behavior

I expected the stack to disappear upon reaching zero or negative numbers.

Start in src/character_inventory.cpp at the i_rem function and reproduce the issue using the attached Damascus-trimmed.tar.gz save. Check how auto-eating glowing mushroom caps handles removal when the stack reaches zero or below. Done means the stack disappears at zero and picking up or moving it no longer causes a stack overflow or crash.
