IMprove registration workflow
If a user gets an invite link https://fairchat.net/invite/QoZNcr and has no fairlogin account, s:he needs to register first. After having successfully registered, the user "looses" the invite link, as the user has to confirm the e-mail address for keycloak first.
Can this procedure be improved? @jbuechele
@bernhard.rieder please test the behaviour as it is now with a dummy e-mail address.
