Don't set non-reusable payment method on Subscription in onPlace event.

IMHO it would make more sense to check whether payment was created from the payment method than to check for a completed order in this case.

That being said, not sure if this should be addressed as a feature request. I am convinced this could be considered a bug for Commerce Recurring. I think an unreusable payment method should not be set on Subscription. One should probably set conditions on payment gateways to avoid situation like this but the Drupal\commerce_recurring\EventSubscriber\OrderSubscriber::onPlace() should still check and prevent setting payment method that is non reusable on the subscripion.

Wrong project :)

In the MR I included fix and test coverage.
