[Lou][2.0.45] Undoing tile change before it is build forgets to undo the basement tile

[Hares]

Steps to Reproduce

1. On Aquilo, have Hazardous concrete as your default heat shield
2. Make a ghost of building requiring heat shielding on Aquilo Ammoniacal ocean via Force build (Shift+LMB)
3. Before it is build, change paving to regular Concrete
4. Wait until everything is deployed
5. Undo twice
6. Wait until bots complete executing deconstruction orders

Expected:

• Everything reverted to the state before you started
• Only endless ocean remains...

Actual:

• Floating Ice platform remains where entity used to be
• No combination of Undo/Redo will get rid of that chunk of ice
