    tracker-extract-desktop: Change how desktop 'Link' files are stored
    
    While this is an API break, the API was added recently and I suspect
    it's not used yet.
    
    The old representation was a problem because the isStoredAs attribute,
    which we use to relate files with their contents, was being used to
    relate the bookmark to the website.
    
    Old output:
    
        INSERT DATA {
          <urn:link:https:%2F%2Fen.wikipedia.org%2Fwiki%2FTracker_(search_software)> a nie:DataObject , 
nfo:Website , nfo:FileDataObject ;
            nie:url "https://en.wikipedia.org/wiki/Tracker_(search_software)" .
          _:1 nie:title "Wikipedia Tracker" ;
            nie:isStoredAs <urn:link:https:%2F%2Fen.wikipedia.org%2Fwiki%2FTracker_(search_software)> .
        };
    
    New output:
    
        INSERT DATA {
          
<file:///home/sam/src/tracker-miners/tests/functional-tests/test-extraction-data/desktop/link-wikipedia-tracker.desktop>
 a nfo:FileDataObject .
          <https://en.wikipedia.org/wiki/Tracker_(search_software)> a nie:DataObject , nie:Website ;
            nie:url "https://en.wikipedia.org/wiki/Tracker_(search_software)" .
          _:1 a nfo:Bookmark ;
            nie:isStoredAs 
<file:///home/sam/src/tracker-miners/tests/functional-tests/test-extraction-data/desktop/link-wikipedia-tracker.desktop>
 ;
            nie:title "Wikipedia Tracker" ;
            nie:bookmarks <https://en.wikipedia.org/wiki/Tracker_(search_software)> .
        };
