BankAccount bank_account_verification field

[eranrund]

Hello,

The bank_account_verification field seems to be of the wrong type:

In [2]: ba = balanced.BankAccount.fetch('/bank_accounts/BA372SBS9pJDmYAAr0tGcSfS')

In [3]: type(ba.bank_account_verification)
Out[3]: balanced.resources.JSONSchemaCollection

In [4]: type(ba.bank_account_verifications)
Out[4]: balanced.resources.JSONSchemaCollection

Am I missing something here? I'd expect bank_account_verification to be the latest one (or None if not present).

Thanks!
