Annotations shouldn't have a link on the annotated content in the Comment tab view

There are several reasons why it's not nice as it's done:

• First, when annotations are not visible clicking on the link will lead nowhere lead the user to think "wtf?"
• Second, it's a little bit strange since it looks as if the link is coming from the annotate content itself. Instead if would be better to add an action button (like we have for edit comment, etc) to go to the annotation place and only activate that button if annotations are visible
