Subject: [PATCH] Makes plumber return matter on deconstruct (#90999)

## About The Pull Request

As in title: make plumbers return matter on deconstruct for plumbing
machinery.

## Why It's Good For The Game

No more matter (and resources) losses, when you mess up with layer
again. And for sake of rebuild and reconstruction - better be able to
have at least something instead of annihilate it.

Video from downstream, but it works the same
