      Problem
      Some users in our crowd.dev prod workspace don't have a user name. It's currently also not possible to change them for others (every user has to go to https://app.crowd.dev/auth/edit-profile for that). The problem is that e.g. assigning tasks doesn't work when there is no user name:
      
      
      Solution
      Auto-set the email address of the user as the name as long as users didn't add their name manually.
