db:seed does not longer try to create invalid user

`rake db:seed` bricht ansonsten mit folgender Meldung ab:

    [heiko@hades ~/Downloads/PINGOWebApp ±master]$ bundle exec rake db:seed
    EMPTY THE MONGODB DATABASE
    SETTING UP DEFAULT USER LOGIN
    [deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
    rake aborted!
    Validation failed - First name can't be blank, Last name can't be blank, Chair can't be blank, Faculty can't be blank, Organization can't be blank.
