Automatically refresh the leaderboard when loading the space

With the current implementation, upon load, the leaderboard is outdated and users need to click refresh to update the results. This button does not actually update the original data (`leaderboard` and `eval_queue`), so upon refresh it's lost. This is also the reason why the `BackgroundScheduler` was not working. So either the background scheduler updates the variables, or we update the data at load time.
