    Fix gsettings tool crash
    
    When no path is provided for the schema, we have call
    g_settings_new() instead of g_settings_new_with_path()
    passing a NULL path.
    
    This was crashing the tool on start since an assertion was
    recently added to g_settings_new_with_path() to refuse NULL.
