Drawn by stalemate

I guess it's something like white definitely wins on points next move regardless (I think 14 points but obv only one piece can be captured), so black doesn't have any legal moves.

The solution I think is for certain types of end result to not count towards move-delegalisation.

Fixed in 1.2.9 with GameResult.soft.
