How can i past a double to a class contructor?

the following doesnt' work
```
$ck = test::double(CacheKey::class, [ 'track' => null,])->make();

$cityConfigProvider = new CityConfigProvider($cityConfigBuilder, $ck); // failed for $ck is not an instance of CacheKey
$ck->verifyInvoked('track');

$value = $cityConfigProvider->get($cityId, 'wechat_app_Id');
```

Start by reproducing the shown test::double(CacheKey::class, ...) setup and the CityConfigProvider constructor call. Inspect how the mocking framework creates doubles for class types; done means the injected $ck is accepted as a CacheKey instance and verifyInvoked('track') works.
