Expand onCallHandover logging and add data enabled check.

There appears to be a case where a call can handover from WIFI to LTE and
ImsPhoneCallTracker thinks data is disabled, even though it is not.
Best I can tell, the ImsPhoneCallTracker must not have been notified of
the correct data enabled state.  I'm now querying this directly from the
DCTracker when we have a handover scenario and logging if there is a
mismatch.

Test: Manual test.
