Bug 28631: Holds History title link returns "not found" error

This patch corrects a broken path in the OPAC holds history page.

This patch also corrects the breadcrumb markup which didn't conform to
the new Bootstrap 4 pattern.

To test, apply the patch and log into the OPAC as a patron who has past
or current holds.

- View the "your holds history" page.
- Click a title link in the table of holds. It should take you to the
  correct bibliographic detail page.
- Check the breadcrumbs of the page. They should look consistent with
  breadcrumb navigation on other pages in the OPAC.
