API Refunds Erroring.

[JamesFX2]

PR on #524 - it's caused by you changing the format of the response from an object to an array.

I'd check $response-> in your extension for other places you've missed it.

For us when making a partial refund via the API the credit memo creation fails but the money is refunded, then the refund webhook calls back and closes the entire order!
