Refine win/loss statistic measurements

Losses are no longer counted since they can be inferred from the existing statistics. Instead, there is now a `minesUncovered` statistics, and redoing an uncovering of a mine will also increase this statistic. Finally, made sure that `wasAutoSolved` cannot be set to `false` again.
