Allow test numbers to be dialed from APM and wait for IN_SERVICE

We now have the ability to distinguish between test emergency
numbers and actual emergency numbers, so we can fix a long
standing testing bug, where you can not place a test
emergency call from APM.

This change now wait for the phone to move to IN_SERVICE
before placing the E911 call.
