Describe the bug

When a user registers he receives the email containing the link to verify the email address.
When the Keycloak server is restarted after the email was sent and the user clicks the link afterwards in a browser incognito window, the server responds with a 500.

This behaviour is reproducible and I can already provide you with a fix.
