Locked user fields are editable when using Manual Auth

In the code the locked fields are getting by $authplugin->config property; in manual_auth_plugin class, config gets all properties by get_config(self::COMPONENT_NAME); in auth_plugin_manual constructor and the constant COMPONENT_NAME is "auth_manual"; in the Moodle DB the locked fields are stored in mdl_config_plugins table in the plugin field as "auth/manual" and other configs as "auth_manual". In CAS accounts, all configs are recorded as "auth/cas" except version that is recorded as "auth_cas"; in cas_auth_plugin class the inherited constructor method get the properties for config by: "auth/'.$authtype". That's correct beacuse in db are stored in the plugin field as "auth/cas".
