Remove 389-ds upgrade state during uninstall
    
    When we perform an upgrade 389-ds is set to listen only on its
    ldapi port. Theoretically it should be restored to the previous
    state regardless of whether the upgrades were successful or not.
    
    To be sure that a subsequent re-install will be successful go ahead
    and remove the state for these options. Think of it as wearing a
    belt and suspenders. Otherwise a re-install could return an error
    message that IPA is already configured.
