Reset Random Leaderboards

In the most recent patch, we adjusted the algorithm for Random Elements so that you no longer get 6-Element builds every single darn game. While this came out as a positive adjustment, it came with an oversight - it screwed over the replays for all the Random Leaderboards.

As a result, we've had to reset them. Not the Pick Leaderboards, those are fine still. Sorry for the inconvenience!
