hackish fix for wikisource portal special case

..because their API URL does not have the "www" prefix
as in the past. either would have to change a whole
lot to save all the URLs for this project in db etc,
or just add this special case for now..

this fixes an error display in the HTML tables, it
makes a red "301" a green "200" and gets accurate data again
for the "www" wikisource wiki
