`avoid_unused_constructor_parameters` false positive in primary constructors

Consider this snippet:

```dart
class C(String name) {
  final logger = Logger(name);
}

class Logger(final String loggerName);
```

The `avoid_unused_constructor_parameters` lint is reported for the `name` parameter, even though its value is used in an initializer for a field.
