Specific Error if refund is created for a payment record that doesn't exist

[harshasomisetty]

instead of returning a general {"error":"\nInvalid prisma.refundRecord.findMany()invocation:\n\n\nInconsistent query result: Field paymentRecord is required to return data, gotnull instead."} error, should return a "PaymentRecord does not exist"

This bug happened when opening a refund for a old payment on shopify dashboard, but a payment that we cleared from our db.
