Before this commit: it was possible to create two PoS terminals in two
companies with the same `adyen_terminal_identifier`. So it's possible,
after each payment, it would add the response to the wrong payment
method's `adyen_latest_response`.

The solution is to bypass multi-company record rule in
`_check_adyen_terminal_identifier`.
