This PR fixes a regression introduces in #33332. If you set the `Expires` header to null when creating a `Response`, the `getExpires` function returned a date instead of null.
```php
$response = new Response(null, 200, ['Expires' => null]);
$response->getExpires(); // Returns a date currently, but should return null
```
