Ecto types return malformed error when casting invalid currency

[bgracie]

When casting an invalid currency, the both ecto types return an error tuple with another tuple as the second element.

money_sql/test/money_ecto_test.exs

Line 72 in bbc4f69

{:error, {Cldr.UnknownCurrencyError, "The currency \"AAA\" is invalid"}}

This violates the typespec for Ecto.Type.cast: cast(term()) :: {:ok, term()} | {:error, keyword()} | :error, and causes an exception when used in Ecto.Changeset.cast

Please see this demo repo for a demonstration of the issue.

Incidentally, it appears that the load functions also violate the error typespec from Ecto.Type.

@bgracie I apologise, I only just noticed this (I need to check notifications on this repo). I’ll fix this right away.
