<CurrencyCode> in invoices endpoint is ignoring lower case currency code
When I send "<CurrencyCode>usd</CurrencyCode>" to a CAD base ledger (with USD as a valid currency) the invoice currency becomes CAD. But if I change it to "<CurrencyCode>USD</CurrencyCode>" then it works fine. (data is coming from Stripe, which uses lower case).
Xero should always capitalize the currency code.
