OboeTester automation buffer_bursts not updating BufferSize UI properly

Android version(s): any
Android device(s): P8 Pro

**Steps to reproduce**
Trigger an automated latency test using:
```
adb shell am start -n com.mobileer.oboetester/.MainActivity --es test latency --ei buffer_bursts 7 \
--ef volume 0.8 --es volume_type music --ei out_channels 1 \
--es out_usage game --es file latency20230608.txt
```

Note the "buffer size = 672 = (7 * 96) + 0" display.

**Expected behavior**
Buffer size radio buttons should reflect the 7 bursts.

**Actual behavior**
UI indicates 2 bursts.
