Evaluating the root object with conform alters other result keys

```js
const Corro = require('corro');
const corro = new Corro();

const schema = {
conform: [{
func: body => !body.thing1 !== !body.thing2,
message: 'either thing1 or thing2 must be specified'
}],
status: {required: true, notEmpty: true}
};

const result = corro.validate(schema, {status: ''});
```

'*' appears erroneously in what should be simply 'status' in the `result.errors` object. Omitting `conform` from the validation schema shows the correct 'status' key.

```json
{
"valid": false,
"errors": {
"*": [{
"rule": "conform",
"result": "either thing1 or thing2 must be specified"
}],
"*.status": [{
"rule": "notEmpty",
"result": "cannot be blank"
}]
}
}
```
