Issue:
sortQueryParameters encodes the query string
Is it supposed to be like this?

**sortQueryParameters: true**

```js
normalizeUrl('http://sindresorhus.com/?url=http://example.com', {
    sortQueryParameters: true
});
//=> 'http://sindresorhus.com/?url=http%3A%2F%2Fexample.com'
```

**sortQueryParameters: false**

```js
normalizeUrl('http://sindresorhus.com/?url=http://example.com', {
    sortQueryParameters: false
});
//=> 'http://sindresorhus.com/?url=http://example.com'
```

Pull request description:
Fix encoding consistency with sorted and non-sorted URL parameters
Fix #149

Currently `normalize-url` encodes URL parameters when `sortQueryParameters` is `true` and leaves them as they are when not. This behaviour is confusing as a user would not expect sorting the parameters to affect the encoding. This PR tries to ensure the search parameters are always decoded, since `normalize-url` already always decodes the pathname and does not intend to sanitize the URL; https://github.com/sindresorhus/normalize-url/blob/6ea4038783d298d499583db07a820e5ca8ff2721/index.js#L160
