Bug 12292: ensure that patrons are not displayed as restricted even when the last restriction has expired

This is the same issue as bug 12134, but for the patron deatils page.

Test Plan:
1) Add a manual restriction to a patron and wait until the
   expiration date of the restriction has passed.  This can be
   simulated by modifying borrowers.debarred for a borrower and
   setting the date in the past.
2) Go on the detail page for a patron (members/moremember.pl)
3) Note the warning message
    "Patron is restricted until XX/XX/XXXX View restrictions"
4) Apply this patch
5) Repeat step 2
6) Note the warning message does not appear anymore
