    YouTube: Try to better handle errors when downloading content
    
    Make sure DataFetch.DownloadContent returns null in case there's an
    exception during the download. This is an attempt to fix bgo#657537.
    
    YouTubeTileData doesn't need to catch exceptions when calling
    DataFetch.DownloadContent, as they are caught inside the method.
