Wrong service fileidentifier in search interface

[armin11]

Check service uuids from https://github.com/mrmap-community/Mapbender2.8/blob/master/http/php/mod_getDownloadOptions.php#L114C10-L114C28 - they should be identical to those which are generated:

• https://github.com/mrmap-community/Mapbender2.8/blob/master/http/php/mod_inspireAtomFeedISOMetadata.php
• https://github.com/mrmap-community/Mapbender2.8/blob/master/http/php/mod_featuretypeISOMetadata.php
