Update Player.php

When a player's account is private and you call GetPlayerLevelDetails() the Containers\Player\Level class cannot be created because $details = $this->GetBadges(); will return empty and the Containers\Player\Level class constructor will fail.

Why do I return NULL so I can just check if GetPlayerLevelDetails () returns NULL is meant there account is probably private.
