Bug 18350: Moving call number in subscriptions tab in OPAC biblio detail

This patches moves the call number up to be under the library name, so
it is equivalent to the staff client

To test:
1) Go to the detail page of a biblio with subscriptions in the staff
client
2) Notice callnumber sits under the library name
3) Go to the detail page of the same biblio in OPAC
4) Notice callnumber is not in the same order
5) Apply patch, refresh page
6) Notice callnumber is now in same order
