Show Briefcase icon not displayed in in-call UI for work SIP calls

Current dialer always queries PhoneLookup._ID and uses this as a contact
ID.

In pre-N, contact id of non-sip query is stored in PhoneLookup._ID and
it is actually a mistake. This problem does not exist in sip query,
and contact id of sip query is stored in Data.CONTACT_ID. So it is a "bug"
in dialer that we use PhoneLooup._ID for sip query as it is not really a
contacat id. The bug of missing work badge may not be the only issue
introduced by this.

In N, the issue is get fixed in framework, PhoneLookup.CONTACT_ID is
introduced. We should access PhoneLookup.CONTACT_ID no matter what
phone lookup query we are having.

The ideal case is we always use PhoneLookup.CONTACT_ID for retrieving
contact id, but given that we need to support in pre-N, we need to
query PhoneLookup._ID for contact id in non-sip query in pre-N.
