How to reproduce :

• go to the demo : https://demo.ametys.org/nightly-intranet/catalog/fr
• Invite an external user to a workspace
• The invited person receives an email
• The invited person creates his account
  *The invited person (unfortunately) clicks on the link in the email a second time redirecting him to the registration form
  It would be good to display a message stating that the user already has an account.
