Hardened against missing entity IDs in Stripe events in the StripeEventService. Updated ValidateCloudRegion to not use a refresh/expansion for the customer because the invoice.upcoming event does not have an invoice.Id. Updated the StripeController's handling of invoice.upcoming to not use a refresh/expansion for the subscription because the invoice does not have an ID.
