DS settings for discussion teaser view
Add  at test (for now without corresponding function) for discussion teaser view
Added test function for branch CFD-172 to prevent future merge conflict.
Added test to check if at least one author field is found on the discussion overview page.
Rename the test so it is clear the test user is looking for a field in an overview
DS settings for discussion teaser and detail view
