Disable client-side validation on credit_note forms
* HTML5 browsers have some clevers to do client-side validation of
forms
* Django activates this by default for certain field types
* However, in this case, there are three forms on this page. We rely
on two of them being invalid in order to figure out what processing
to do.
* So we need to disable the client-side validation.
