[Bug 0.71] Decommissioning a starbase also scraps the defending fleet

I accidentally built a starbase with a Military Ring instead of a Mining Ring. I had 3 tiny fighters and a small missile frigate defending the starbase. When I destroyed the starbase I lost the defending fleet as well. If this is intentional the popup box should read "Are you sure you want to decommission this starbase and it's defending fleet?" instead of "Are you sure you want to decommission this starbase?".
