Bug 17316: Do not display the list's name if the user does not have permission - OPAC

At the OPAC, if a user manipulate the URL to show a list (s)he is not
allowed to view, the list's name will be displayed anyway.

Test plan:
- Create a private list with user A
- Copy the op=view URL and access it with user B logged in
=> Without this patch, you will see the rss icon, the list's name and
the "add list" button
=> Without this patch, only the "unauthorized" box will be displayed

Followed test plan, works as expected.
