    Fix password manager for forms with no username
    
    In 8036139d, I once again broke the password manager for forms with no
    username. I think I will continue to break the password manager every
    time I make any change to it, so long as we don't have any tests.
    
    This reverts 8036139d and ensures we pass along a null formAuth when
    there are no results, like we used to do.
