Question result data duplicated in 'passed' and 'attempted' statements

Both the 'passed' and 'attempted' statements include a result object like:

```
"result": {
        "score": {
            "scaled": 1,
            "raw": 1,
            "min": 0,
            "max": 1
        },
        "success": true
}
```

Sending this data in both statements can lead to double counting in reporting tools like Watershed.
