Bug 28004: Fix breadcrumbs on authorised_values.tt

To Test:
  - go to a category with at least one value, see the complete breadcrumb "Home › Administration › Authorized values › Authorized values for category" with link on the 3 first menus
  - create a new category / go to an empty category ; see the incomplete breadcrumb "Home › Administration › Authorized values" with link only on the 2 first menus
  - Apply patch
  - go to category with at least one value, breadcrumbs should look like Home › Administration › Authorized values › Authorized values for category CATEGORY
  - got to category with no values, breadcrumbs should look the same as category with values
