Paper index page should have a link to delete a paper

[swt2public]

Given a paper
When users visit the papers index page
Then it should have a destroy link

Expected to find css "a" with text "destroy" but there were no matches. also found "show", "edit", "add paper", which matched the selector but not all filters.
