bug(linter) error in fixer for perfer to have length

See https://github.com/bbc/simorgh/blob/latest/src/app/legacy/containers/StoryPromo/index.test.jsx

```ts
        expect(assetTypeContainer.getElementsByTagName('time').length).toEqual(
          0,
        );
```

is being fixed to 
```
expect(assetTypeContainer.getElementsByTagName('time')).toHaveLength 0,
    );
```
which is incorrect
