Retractions link is missing in the article comments tab

[rcave]

If a retraction annotation type is added to an article, then the default Ambra journal template needs to include a link to the retraction in the "Comments" tab. There will only be a single retraction for an article. Determine that a retraction has been made and change the link to "View retraction". There may be one or more formal corrections in addition to a retraction.

Verified that the retraction link is appearing correctly in the Comments tab. Verified that if a retraction and a formal correction is on an article, the link in the Comments tab only display "View Retraction."

Formal corrections and retractions are not showing in the Comments tab. The number indicates that there is an annotation, but there is no link to read the formal correction or retraction. Confirmed that this occurs in CompBiol? and Genetics templates. Unknown if other templates have the same error.

This error occurs when there are no notes/comments/ratings on the article. Once an annotation is added, then the link is displayed correctly. The link to a formal correction or retraction should always be displayed regardless of 0 -> n other types of annotations.

(In [7450]) Reworked logic for what displays when on the article comments page. This improves the UI a bit, and fixes at least one bug.

The retraction is only displayed on the comments tab in the default Ambra template. The other journals are not displaying the retraction on the Comments tab.

Other journals or just plosone? The CVS templates for PlosOne? were out of date and have been updated. Other journals should be using the default templates.

Verified that the retraction link is appearing for all journals.
