    audioscrobbler: don't save submission queues without a username
    
    Queues saved without a username are saved as
    ~/.local/share/rhythmbox/audioscrobbler/submission-queues/servicename
    which prevents the creation of the directory used to store queues
    saved with a username.  This data can't be submitted to the service,
    so there's no point saving it.  Since it interferes with proper operation
    later on, remove such a file if we find one on startup.
