[4.3] KZOO-96: Resolve emergency email number (#6678)

When e911 call is made from number different than number which has
e911 active, make sure to resolve proper address and info. Also make
sure to not try to send emails for e911 calls made using local carrier
as we only care about numbers which have e911 activated and have email
address setup for that.
