* Fixes racks not crafting properly and deleting themselves (#72164)
## About The Pull Request
Rack parts now use get_turf instead of loc when being constructed from
your hands. Loc would be the user rather than a valid location, and the
rack parts would be consumed, meaning you lose your rack parts and get
no rack. Loc is used in a few other places in the racks/tables file, but
they all appear to be working fine other than this one instance.
## Why It's Good For The Game
We've gotta keep our stuff organized somehow, right?
Closes#72155
