LP1873539 Active column in SMS carrier configuration

This fixes the lack of values displaying in the Active column of the
SMS Carrier configuration screen.  (Administration->Server Administration->SMS Carriers)

To test apply the patch.
Go to the Carrier Configuration screen and note that the 'Yes' and 'No'
boolean values now display for the Active column.
