* improve emergency emailing
1. set emergency CID name & number to the outbound CID name & number if emergency CID name & number are not set
2. remove duplicate item in email body
3. change the hardcoded email subject '911 Emergency Call' to be dynamically provided from the event. I do not like seeing the subject '911 Emergency Call' when it is an TEST call.
