Describe the bug

In old games published with a leaderboard on GDevelop silver (legacy) plan, there was no requirement for users to sign-in to use the leaderboard. But now the behavior is changed to make it mandatory for users to sign-in to claim their score. This is not the same behavior as when the game was published and requires us to make changes to all our older games. The sign-in button does not even work in these older games.

Steps to reproduce

1. Play an old GDevelop game developed with a leaderboard before it was possible to sign-in.
2. It will require you to sign-in when viewing the leaderboard.
3. The sign-in to claim your score button doesn't work.
