Bug 33395: Patron search results - show number of overdues and checkouts when patrons have overdues

This fixes the display of patron search results, so that it shows
the number of checkouts when a patron has overdue items. For
example: 1 / 2

Bug 30063 changed the display to show only the number of overdue
items in bold and red, without the total number of items checked
out.

Test plan:
1. Check out two items to a patron - make one overdue (click the
   checkout setting options and then specify a due date a month
   ago).
2. Check out another item to another patron.
3. Search for patrons so that the two patrons you checked out
   items to are listed in the results.
4. Note the display for the 'Checkouts' column:
   4.1 For patrons without any checkouts: 0 / 0
   4.2 For the patron from step 2 with one checkout: 0 / 1
   4.3 For the patron from step 1 with one overdue and one
       checkout: 1 (in bold and red)
5. Apply the patch.
6. Refresh the page of results (step 3).
7. Note that for the patron from step 1, the display now shows:
   1 / 2 (with the 1 in bold and red).
8. Sign off! 8-)
