Description
Please describe the issue:
Hi!

When I run the app with `.storekit` configuration file added to scheme in Xcode 12.2 (latest AppStore version) / iOS 14.2 Simulator, my `SKReceiptRefreshRequest` always fails, I get an error in my `func request(_ request: SKRequest, didFailWithError error: Error)` delegate method.

Same error happens when I run my StoreKit tests with `.storekit` file configured.

Everything worked fine on previous Xcode release, so I suggest this is a regression. I restarted both simulator adn Xcode, but that didn't help.
Please list the steps you took to reproduce the issue:
1. Add correctly set up `.storekit` file to scheme, run the app in iOS 14.2 Simulator
2. Run `SKReceiptRefreshRequest` at some point (I use the button for that)
What did you expect to happen?
I expect `SKReceiptRefreshRequest` to finish with success and delegate method func `requestDidFinish(_ request: SKRequest)` to be called
What actually happened?
Delegate method `func request(_ request: SKRequest, didFailWithError error: Error)` is called with this error:

```
Error Domain=SKErrorDomain Code=0 "UNKNOWN_ERROR" UserInfo={NSLocalizedDescription=UNKNOWN_ERROR, NSUnderlyingError=0x600003c9a040 {Error Domain=ASDServerErrorDomain Code=5002 "Unhandled exception" UserInfo={NSLocalizedDescription=Unhandled exception, NSLocalizedFailureReason=An unknown error occurred}}}
```
