Don't call item::put_in on full brass catcher

[kevingranade]

Summary

SUMMARY: None

Purpose of change

Fixes #44151
The brass catcher would overflow and print a message when it did so.

Describe the solution

Check if the brass catcher had room for a casing before attempting to insert it.

Describe alternatives you've considered

A more invasive fix was attempted in #44155, but at the end of the day I don't like the approach of silencing the check if the caller claims to handle it instead of insisting that the caller should always insure that the insertion will succeed.

Testing

Spawned a gun, attacked a brass catcher, fired it until the brass catcher filled up and started dropping casings on the ground.

Just wanted to mention I did not do it like this because can_contain does the exact same checks that put_in already does.
