Add failing tests due to Some(quantity) in send methods

simple_bolt12_send_receive is failing due to unexpected behavior.
When quantity is Some in send we get a InvoiceRequestCreationFailed
error and in send_using_amount we get a PaymentSendingFailed error.
initiate_refund is the only bolt12 method that is successful when
a the quantity is Some.
