This makes the logs a bit more useful to search requests by users.

Without this fix, we would just see redundant entries in the `params` section:

```
{"method":"GET","path":"/-/metrics","format":"html","controller":"MetricsController","action":"index","status":404,"duration":1.42,"view":0.38,"db":0.0,"time":"2017-07-28T02:59:18.167Z","params":{"controller":"metrics","action":"index"}}
```

The intended format looks more like this:

```
{"method":"GET","path":"/-/metrics","format":"html","controller":"MetricsController","action":"index","status":404,"duration":76.32,"view":69.95,"db":0.0,"time":"2017-07-28T02:59:48.893Z","params":{}}
```

The proper form to exclude an array is to preface with an asterisk:

- `scope`: Return merge requests for the given scope: `created-by-me`, `assigned-to-me` or `all`
