Nesting big bag tests and fixes for disapearing items

Purpose of change

Potential fix for a bunch of issues I can't find related to disappearing items when using holsters.

Describe the solution

Basically when you had restrictions and rules on a pocket the nesting rules got a lil' wild with where they would try to put stuff. So sometimes stuff would end up being too large of volume for where it could go. This would usually be caught by best pocket when actually doing the insert but you would already be mid trying to insert so sometimes the item would be irreparably deleted.

I've added to the recursive call the ability to check the parents remaining volume so that if a pocket that you think "can" contain an item isn't rigid it'll check if it'll become too big to fit.

Describe alternatives you've considered

Testing

Added a unit test for this behavior. The basic case is:
Add a small worn bag to the character, insert into it a larger bag, add some sort of whitelist on the worn small bag, try to pick up something that would fit in the big bag but not the small bag. Before it would say you could then throw errors, now it will properly say that you cant.
