[FIX] website_form: fix wrong user sending website forms

Issue
	- Set outgoing mail server
	- Install Online Ticket Submission
	- Publish an Helpdesk Team
	- Log out
	- Create a ticket from the helpdesk form

	The user who created the ticket is "Public User"
	He has no email address, so the mail is not sent

Cause

	insert_record method in website_form/main.py uses .sudo()
	In v12 => sudo replaces the user in env by the superuser => ok
	In v13 => sudo adds a flag "su" and does not replace the user in env

Solution

	Add a with_user(SUPERUSER_ID) to the create method's call in
	insert_record
