Resetting battery status makes the "disabling battery saver mode"
operation that follows it a no-op if the device is plugged-in to power.
In this case, sticky battery saver status won't get reset and might
affect the tests following it.
Also, change back turnBatteryOff -> "cmd battery reset" since issue "72502904"
is fixed now.
