Include fact check request recipients in note

Refactor led to a regression where if a user provided a comment along
with a fact check request, the email addresses wouldn’t be displayed.

* Show both comment and email addresses
* Include test to document behaviour
* Format mailto address to remove spaces, a mailto which contains
spaces is an invalid link
Avoid submitting business support form with JS

The update action for an edition relies on the value of the commit
button submitted with the form. By intercepting the form submit and
resubmitting after a DOM modification we lose that context.

* Don’t prevent default and avoid submitting form with JS
* Instead let the event bubble up and perform its default action,
submitting the form as the user originally intended

(This only seemed to be a problem within Firefox)
