Update unread news items in --pretend mode.

This has been disabled since commit
c7faa634369e61b87a40172ceb0a5cb9494fd518, but the only reason cited
was to avoid permissions issues. So, go ahead and enable it, and handle
PermissionDenied just in case. NOTE: The NewsManager typically handles
permission errors by returning silently, so PermissionDenied won't
necessarily be raised even if we do trigger a permission error.
