Clear out current auction price at the end of an auction

[rowgraus]

Describe the bug

After a liquidation auction, the auctioneer continues reporting the "current price" as the final step in the auction

To Reproduce

Run a liquidation auction and observe!

Expected behavior

Price should be either zeroed or N/A

When I look at the place I thought I would need to fix this, it's already doing the right thing.

Do you remember where you observed the current price after the end of an auction? Have you seen it do this recently?
