Bug 11429: Add a link to basketgroup in basket detail page

If a basket is in a closed basketgroup, the basketgroup name is
currently displayed.

This patch adds a link around the basketgroup name if the librarian
has permission to manage basketgroups.

Test:

A. With a librarian with rights for managing basketgroups
Display a closed basket that is grouped in a basketgroup
Check the name of the basketgroup is now a link
Click on the link and check you are seeing information about the
right basketgroup

B. With a librarian WITHOUT rights for managing basketgroups
Display a closed basket that is grouped in a basketgroup
Check the name of the basketgroup is not a link
