Name changes fail to update if the same name already exists with a different uuid.

Name changes fail to update if the same name already exists with a different UUID in the database already.

Simplified example:
Player A (uuid 1) logs in, is added to the database.
Player A (uuid 1) changes their name to B.
Player C (uuid 2) logs in, is added to the database.
Player C (uuid 2) changes their name to A.
The database does not update the uuid for A, so A remains in the database with uuid 1 instead of uuid 2, and the entry under name C remains, although that UUID should now be associated with A.

Name in the database was legacy data, but seeing as it can be useful knowlege im marking this as both a bug and an enhancement.
