Minor mapcut fix (#3919)

## About The Pull Request

As is in the title, fixes a small error in the maptainer mapcut PR

## Why It's Good For The Game

Instead of corporate mining being removed in the ruin datum,
bigderelict1 was instead removed in said datum, causing corporate mining
to be spawned instead with nothing. Fixes that so derelict1 exists again

## Changelog
