LP#1454871: Fix KPAC Hold Notification Preferences

Correction to KPAC holds notification default preferences to allow for
SMS text messaging options.

Prior to this correction, KPAC hold notifications would only pick up
hold preferences if set to email and/or phone. This correction allows
it to pick up email and/or phone and/or sms notification preferences.

To test, set hold preferences to different options, place hold via the
KPAC and then view the hold to see which preferences were recognized.
