[FIX] mail: uncheck recipient without partner

To reproduce
============
- on website add or edit **contact us** form to create a task on a project
- fill the form from Incognito
- on project -> the created task : try to send message on chatter
- you will find the email used when filling the form with possibilty
to check it as receiver
- check the box, a dialog will open to create a Partner for this email
- close the dialog without modifying anything

Problem
=======
the checkbox will remain checked, but when you send a message no email will be sent

Solution
========
as stated in this comment https://github.com/odoo/odoo/blob/de1f701e7bd7ebb6f7ebea5c097d980039c4f904/addons/mail/static/src/components/composer_suggested_recipient/composer_suggested_recipient.js#L128-L130
we will only send the message to partnenrs, so if no partner is
created we must uncheck the checkbox.
