Bug 21293: Display of housebound delivery information broken by Bug 13618

This patch corrects the patron housebound details template. A stray
"html" filter broke display of delivery information.

To test, apply the patch and enable the HouseboundModule system
preference.

 - Open a patron record and select the "Housebound" tab in the left-hand
   navigation menu.
 - Click "Add a new deliver" and save some delivery details.
 - Upon saving you should be directed back to the housebound details
   page. All the details of the delivery you saved should appear
   correctly.
