Add check for href value to sampledFeature insertion. If the href value is http://www.opengis.net/def/nil/OGC/0/unknown, no sampledFeature with identifier http://www.opengis.net/def/nil/OGC/0/unknown is inserted.
If old settings are loaded, the initialization fails during the setting of SosServiceIdentification title and abstract because the parameter changed from String to MultilingualString.
