SP uninstall attempts to run install
    
    When running 'ipsilon-client-install --uninstall' to uninstall a SP,
    we call the install routine again after completing the uninstallation.
    This leads to confusing error messages about missing required options.
    This patch corrects the uninstallation logic.
