quick fix create method doesn't create named params

When quick fixing the following code (method used but not declared):

```
      tryToAutoConfigure(complainOnFailure: false);
```

it creates the following method declaration:

```
  void tryToAutoConfigure(bool arg0) {
  }
```

Where, it should create something like:

```
  void tryToAutoConfigure({bool complainOnFailure}) {
  }
```
