Summary: On re-purchase of a non-consumable item, the app receives a failure message that cannot be distinguished from the user cancel event

Steps to Reproduce: 
1. Setup your app for In-App purchase with non-consumable items
2. Purchase an item
3. Apple dialog appears: "Purchase was successful"
3. Purchase the same item again
4. Apple dialog appears: "Item was purchased already. Tap OK to re-download".

Expected Results: App re-downloads the purchased digital good

Actual Results: App does not re-download because it cannot distinguish the received failure message from a user cancel event

Regression: -


Notes: 

These are the calls received in the app (in StoreKit callback (void)paymentQueue:updatedTransactions:):

SKPaymentTransactionStatePurchasing
SKPaymentTransactionStateFailed

The received error code 2 is the same as when the user cancels the purchase. The SKPaymentTransaction does not have a receipt either.
So there is no way for the app to know that a re-download is requested here although Apple's StoreKit dialog tells the user differently.

Is this a iap sandbox only defect??
Today I experienced these two different sequences on re-purchase of an in-app-purchase item:

1. (as described in this bug)
i. SKPaymentTransactionStatePurchasing
ii. SKPaymentTransactionStateFailed

2. (expected behavior)
i. SKPaymentTransactionStatePurchasing
ii. SKPaymentTransactionStatePurchased
iii. removedTransactions

What is the sequence of updatedTransactions callbacks we can expect to receive on re-purchase?

Steps to Reproduce [Updated]:

1. Setup your app for In-App purchase with non-consumable items
2. Launch app
3. Purchase an item
4. Apple dialog appears: "Purchase was successful"
5. Quit app
6. Make sure to not be logged in at Settings > Store
7. Launch app
8. Purchase the same item again
9. Apple dialog appears: "Item was purchased already. Tap OK to re-download".
10. -> SKPaymentTransactionStateFailed

This bug is in sandbox and production environment of iap. It seems to be caused by internal session management. With a stable session established already (logged in via Settings > Store), on re-purchase the app receives SKPaymentTransactionStatePurchased after SKPaymentTransactionStatePurchasing (as expected).
