[FIX] website_form: binary work with website_crm_phone_validation

With this change, a binary field in a website form works when
website_crm_phone_validation (website_crm in 13.0) is installed.

The module website_crm_phone_validation would call `extract_data` method
to do some things, but when extract_data was called a second time to
really save data, the FileStorage werkzeug object would already consumed
and files would erroneously appear as empty.
