Mark missed calls as read in calllog restore(2/2)

When missed calls are restored by CalllogBackupAgent using the addCall
API of CallLog provider, we were setting the IS_READ flag to 0 which
resulted in user getting a missed call notifications for all missed
calls after restore.
Adding a new addCall API signature which can specify the value to be put in the
IS_READ field when a call is added to the calllog provider. This will be
used by the CallLogBackupAgent to mark all restored missed calls as
read.
