Fix: Fill in the phone number info for outgoing call 

There're two cases of outgoing call: dial from HF or dial from
phone. We could receive callsetup=2 indicator in both case. So
adding AT+CLCC query to sync the outgoing call.

In the first case, we only need to sync the phone number.  In
the second case, the phone is dialing from phone and we know
nothing. Create a new call and notify the core.

If phone does not support AT+CLCC and there's no call dialing
from HF, we fake a new call for it.
