Fix cell stats did not increase due to rate limit in battery stats
Current test triggers batterystats to update mobile stats by
switching default network and ConnectivityService will call
reportMobileRadioPowerState to have batterystats update the
mobile stats. But in current design, batterystats will
rate-limit the update if it is due to modem power state change.
So the modem stats might not be updated if it's rate-limited.
The other reasons (plug/unplug, battery level change,etc) will
be unaffected. Thus, dump battery stats in the test to trigger
a full sync of data.
