Removes self-linking article title

# Link not unto thyself
When linked article titles are enabled titles are not only linked to from blog, featured and list pages, but also in the article view itself.  This is clearly nonsensical, as the linked title of /my-awesome-post links only to /my-awesome-post.

This PR removes title linking in the article view.

## Test
After applying this patch an article title will no longer pointlessly link to itself, saving link-juice, mobius-logic and link-colored pixels.
