Player cell in the early multicellular prototype can get damaged if another colony cell's pilus gets hit with a toxin (physics engine bug)

[stoptakingusernames]

Describe the bug

If your multicellular organism contains another cell with a pilus, all the damage that would happen to the specified cell would instead transfer to the player cell if a toxin shot hits the specified cell's pilus

To Reproduce
Steps to reproduce the behaviour:

1. Enter the early multicellular prototype
2. Create a new cell with a pilus and add it to your organism
3. Let the added cell's pilus get hit with a toxin shot from an enemy cell
4. See the player cell being damaged instead

Expected behaviour
The toxin should damage the cell that has the pilus, and not the player cell

I'm 99% sure that this is a Godot physics engine bug where it gives us an obviously false sub shape index (it does that a ton), and we can either guess something or assume the colony lead cell got it (this is the current behaviour).
