## About The Pull Request
- Fixes#81289
It has nothing to do with `dump_contents()` but with the material
container that drops its materials on `Destroy()` causing side effects.
Now it only drops sheets when an object is deconstructed but not
destroyed.
For this to work properly on all instances we have to ensure
`deconstruct()` is not overridden at least on machines for now, so they
can send `COMSIG_OBJ_DECONSTRUCT` signal. That comes in the next PR

fix: deleting objects with local material storage(autolathe, drone
dispenser etc) no longer drops sheets, they only drop materials when
deconstructed
