Populate 'hasKnownUserIntentEmergency'

This is only used to specify when the dialed number is ambiguous,
identified as both emergency number and any other non-emergency number;
e.g. in some situation, 611 could be both an emergency number in a
country and a non-emergency number of a carrier's customer service hotline.
