Refine the original workaround patch in the ag/15527095 from NPE to
return default BatteryUsageStats instance as we merged in the

In some corner cases, we will receive the DeadSystemException from
BatteryStatService when invoking getBatteryUsageStats() method. Before
this issue is resolved by BatteryStatService team, we will add some
protections to avoid Settings app is crashed.

For now, keep both BatteryStatsHelper and BatteryUsageStats in play.
The plan is to transition from the former to the latter, one usage
at a time. When all is said and done, all references to
BatteryStatsHelper will be gone.
