Bug 31724: Remove 'i' from breadcrumb when deleting a MARC framework subfield

Remove 'i' added to the end of the breadcrumb on the confirmation page
when deleteing a MARC framework subfield.

Test plan:
1. Go to Administration > MARC bibliographic frameworks.
2. View the subfields for a tag for a framework, for example:
   . BKS framework > Actions > MARC structure
   . Search for tag 245
   . Select Actions > View subfields.
3. Select any subfield to delete and select the Delete button.
4. Note that there is an 'i' at the end of the breadcrumb, for example:
   . ... > Confirm deletion of subfield bi
5. Apply the patch.
6. Refresh the page and note that that 'i' is removed.
7. Sign off.
