Switchvox - Extension Permissions mapping does not require Extensions to be selected

SWVX-12412 Extension Permissions mapping does not require Extensions to be selected

Validation Date: 1/12/2018
Affects Version: 6.6.0.1 - 6.6.0.4
Resolved Version: 6.7

Description: Under Setup -> Extensions -> Permissions -> Create Extension Permission Mapping, you are able to select the Permission Holders type and save the page without adding any extensions or groups. This causes the permissions to be ineffective since they have no target.
