Bug 29820: Set paging option using boolean instead of string

Bug 28450, "Make Account summary print tables configurable," added
DataTables to the print summary view. The updated page includes the
wrong option:

"paging": "false",

It should be:

"paging": false,

Because DataTables expects that option to be boolean (true or false).

To test, apply the patch and check out to a patron who has more than 20
checkouts and more than 20 holds.

 - From the toolbar, click Print -> Print summary.
 - On the acount summary page, confirm that the "Items checked out" and
   "Pending holds" tables show ALL entries, not just the first 20.
