[BUG] Correct name check on PaperSpigot

:round_pushpin: Description (REQUIRED)

What behaviour is observed:

After a player changed their premium username - FastLogin still forces an old username to be used. Also because of that - premium register/login is not working for that person and he has to log in manually

What behaviour is expected:

should recognize the change, update the database and not force the old username

Steps/models to reproduce:
