Hide emergency callback number when slot2 SIM is default.

Because emergency calls are always made from the SIM in slot1, when
slot2 has the SIM set for default outgoing call, the InCallUI currently
thinks the emergency callback number is different from the number being
called from (the code only uses the default number). The fix is to check
the line 1 number of the phone account being used instead of the default
phone account.
