Bug 16568 - Talking Tech generates phone notifications for all overdue actions

Bug 16568 - Talking Tech generates phone notifications for all overdue actions

Regardless of whether the phone transport has been selected for a given
overdue action or not, the Talking Tech outbound script generates and
sends a line for that action.

Test Plan:
1) Enable Talking Tech
2) Create one or more overdue actions without a phone transport selected
   and one or more with the phone transport selected
3) Generate the overdues csv file to send to Itive
4) Note the csv file has lines for actions that do not have the phone
   transport selected
5) Apply this patch
6) Repeat step 3
7) Note the csv file now only has lines for actions that have the phone
   transport selected
