Add the ability to upload score after game restart

[f1amy]

For some time my game struggles to upload a score+replay to the BeatLeader.
Usually it takes a minute and maybe a retry to upload.
But sometimes I'm forgetting about it and start a new play or exit the game, only to realize that I failed to upload a score.
It's frustrating to make a new best score on a difficult map and not get it uploaded to get those sweet PPs.

Can we have a way to upload a score+replay to the leaderboard after we had played other map or after game restart?
