Bug 19291: Make breadcrumbs for OPAC search history consistent with other patron account pages

This patch adds the logged-in patron's name to the search history page's
breadcrumb navigation.

To test, apply the patch and view the OPAC search history page with no
user logged in. The breadcrumbs should read:

- Home ->  Search history

Log in and return to the search history page. The breadcrumbs should
read:

- Home -> Owen Leonard -> Your search history
