[FIX] auth_signup_verify_email: Use reCaptcha

[Cl0ut1eR]

#774 (previous pr with same changes #775 )

Fixes an issue when using the reCaptcha addon together with auth_signup_verify_email. Currently, passwordless_signup() bypasses the reCaptcha check in the original web_auth_signup() method.

The root cause is that _verify_request_recaptcha_token() is supposed to remove the token from the request, but the same request is then used directly for user creation, resulting in: ValueError: Invalid field 'recaptcha_token_response' on model 'res.users'

Isn't reCaptcha an extra module?

Isn't reCaptcha an extra module?

Yes but the original implementation of the method _verify_request_recaptcha_token is from base.
