Removing gun- or toolmods with pocket_mods updates the pockets

[mqrause]

Summary

None

Purpose of change

Removing a mod with pocket_mods didn't update the pockets, that only happened when inserting mods or loading a save.

Describe the solution

For a lack of determining what kind of pocket an item was removed from, update pockets when removing any item from any pocket.

Describe alternatives you've considered

Testing

Extended the test to also cover removing the mod again and it passes locally.
