Improve CallLogProvider logging to help in issue diagnosis.

Added LocalLog which logs the last few calls we have logged to the call
log.  This helps ensure we can quickly reconcile when Telecom says it
has logged a call to what the provider actually knows was logged.

Bug: 290557274
Test: Manually tested new logs and dumpsys for call log provider.
