Set the registrar WHOIS email in the web console creation endpoint

We set the initial value to the "icann referral email", but registrars can change it later if they want.

Although this value isn't strictly required, we assume it exists in the spec11 report.

Also changed the name of the contact email from "email" to "consoleUserEmail"
