bug: error in payment-onCreatedFunction during payment integration tests

[jeromevdl]

When deploying payment module (make all-payment), there is an error in cloudwatch logs for the payment-onCreatedFunction:

[ERROR] KeyError: 'paymentToken'
Traceback (most recent call last):
  File "/var/task/main.py", line 43, in handler
    payment_token = event["detail"]["paymentToken"]

Looking at the event, we have an OrderCreated event, mixed with a PACKAGING_FAILED status and actually no paymentToken:

        }
    }
}

The problem comes from the integration test (test_on_failed_warehouse): https://github.com/aws-samples/aws-serverless-ecommerce-platform/blob/969f6f89a7e2071f28a9f6c728fc7d6dc8adfd2f/payment/tests/integ/test_on_events.py#L147

Same error and quite similar event for the test_on_failed_delivery: https://github.com/aws-samples/aws-serverless-ecommerce-platform/blob/969f6f89a7e2071f28a9f6c728fc7d6dc8adfd2f/payment/tests/integ/test_on_events.py#L204
