Fixes lathes breaking on ore silo deletion (#91498)

## About The Pull Request
- Fixes #91494
- Fixes #91479
- Fixes #90533

The ORM disconnects the machines from its `Destroy()` proc by which time
its deleted flag has already been set to TRUE leading to an early
return, thus causing the silo to not disconnect properly
