### Issue summary
Calling SwiftyStoreKit.verifyReceipt returns receipt with 200 old auto-renewals but no non-renewable purchases.
SwiftyStoreKit.verifySubscription for nonRenewing product then says .notPurchased even though I bought it 2 minutes ago.
Is there a limit for "in_app" list ? Is this just a sandbox thing or can this happen in production ?
We're moving from auto-renewable to non-renewable subscriptions and sandbox account with lots of auto-renewals is unable to restore purchases because of this. Other accounts with less or none auto-renewable items work fine.

### What did you expect to happen
verifySubscription should find the latest non-renewable subscription purchase

### What happened instead
verifySubscription returns .notPurchased
