### Steps to reproduce

1. I make a subscription purchase on an Android device.
2. I do not invoke `completePurchase` after receiving the `PurchaseStatus.purchased` status.
3. I relaunch the application.

### Expected results

The purchaseStream should return all payments that have pendingCompletePurchase = true, so that the product can be granted if it wasn't done immediately after the purchase.

### Actual results

Despite the function that starts listening to the stream being called in the main application, when the app is launched on Android, the stream is not invoked and does not pass on ungranted but paid purchases. As a result, I am unable to grant the user the purchased subscription.
When I go into the subscription settings (google play acc), I see that it is waiting to be granted in the app.

I am testing the whole process with draft payments, but I have built the app in both debug and release modes.

    purchaseSubscription = _inAppPurchase.purchaseStream.listen(
      _purchaseUpdateListener,
      onError: (e) {
        // TODO: error handling
      },
    );
  }
