Bug 22330: (QA follow-up) Enable datatable in patron search

Test plan:
Try to search patron for circulation (or for creating hold), when there
are more than 1 patron, you should see a table with patrons found.
--> without this patch, the datatable is not created (for example
        sorting the table by clicking to column heading does not work)
--> with this patch, the datatable works
