Fix logging two call records for emergency call

When making one emergency call, the lower layer may return unspecific
error, so that Telecom continues performing the call in next phone
account. Due logging the call record is later than changing the call
state, so the phone account is replaced with next phone account before
recording the call log for previous phone account. After retry, even
Telephony redirects phone to same phone object, but actually Telecom
also records two call logs for different phone account.

To fix it, when continuing to try emergency call in next phone account,
do not trigger callback for call state change to avoid logging an
incorrect call record, also avoid abandoning audio focus.
