Minor issue that needs a backend fix.

[MitchExpensify]

@IuliiaHerets I don't see a 400 error in the video, am I missing something?

[IuliiaHerets]

@MitchExpensify Can you please check the last 5 seconds of the video?

I believe this needs a simple backend fix because api/BankAccount_CreateCorpay? is returning "400 invalid IBAN" as the error message.

While it should just return "Invalid IBAN".
