Error when including both issuer and pricing.

[martijnmelchers]

When using the method GetPaymentMethodListAsync() the function gives an error when you both request the issuers and the pricing.

The following error appears:

ArgumentException: An item with the same key has already been added. Key: include

This is because it adds the "include" key and doesn't append to it.
