Fix morph link for broken scrapers.

On the authorities pages the morph scrapers that report as possibly broken are linking to scraperwiki where a url is available, all of these links are returning a 500 status from the scraperwiki site, fixed the links to point to the morph url.

Removed scraperwiki links in general as they are all broken anyway. I didn't removed them from anywhere but the view as I wasn't sure if the urls are still needed elsewhere.
