create_and_destroy will no longer spawn abstract types (#95071)

## About The Pull Request

What it says on the tin-- with having a nice abstract types system now,
we can utilize that in create_and_destroy.

## Why It's Good For The Game

Removes a lot of the need for snowflake item exclusions, and makes this
test likely a lot more stable (and a little faster even).
