[FIX] website_form: website form type in form parameters

In 13.0 odoo/odoo@6404233bb0 adds a new website_form_key field that was
not taken into account when creating a form from website studio.

This would cause that when editing the form, we would not see it in the
list of form type, and so think it was doing another action that the
current one. And if saved that could cause an issue because the form is
now for doing something else and no way to change it back.

With this changeset, we get back to what was before 13.0 and display a
model in the "Change Form Parameters" modal even if it has no associated
form in the registry (through a website_form_key).
