Refactor ECC Support: Update when EFecc is read 

We should start with a default set of ECC numbers which are always
available according to 22.101, even if no SIM present.  Then when
EFecc is read, we update the EmergencyNumbers property.  According to
22.101 the 112 and 911 numbers must always be available.  Since these
numbers can also be stored on the SIM itself, we must avoid duplication.
