UUID get cleared if Login from Bedrock(Floodgate)

[HuJK]

What happened?

autoRegister: false
premiumUuid: true
nameChangeCheck: true
autoLogin: true
autoLoginFloodgate: linked
allowFloodgateNameConflict: linked

FastLogin should be able to remember the UUID of an player to do nameChangeCheck.
But Login from Bedrock client by linked mode clears the UUID of the player.

Before Bedrock Login

After Bedrock Login

Steps to reproduce

1. Install AuthME, FastLogin Geyser-Spigot Floodgate
2. Register at FastLogin as premium user. Now it should be able to track name changes
3. then link the bedrock account at Floodgate
4. Login to the server at Bedrock client through Geyser-floodgate
5. The UUID has been cleared at the FastLogin database.
6. If user changes his name before next login at Java client, FastLogin can't reconize and treat him as a new user. (No UUID nor username not found in the database)

Player UUID get overwrited by session UUID(which is null) at ForceLoginManagement.java

It seems that this problem is caused by session UUID are not set if player login from Floodgate
