Makes the turbine core part remove references on deactivation (#80593)

## About The Pull Request
The delete the world test was showing that the turbine's non-core parts,
the compressor and outlet were causing runtimes, so I made the
deactivation of the core remove the references from the secondary
turbine parts
## Why It's Good For The Game
Less harddels means less lag, hopefully
