Wrong links when clicking on new accounts on the events page

One-sentence description

Wrong links when clicking on new accounts on the events page

Current behaviour

With the new accounts of the 'sjaars', when you click on one of them on the bowling page, it redirects to the wrong account.

Expected behaviour

When you click on a new account (I think it only happens with cohort 2017) it should go to the correct user.

Steps to reproduce

  1. Open the Bowling page on thalia.nu
  2. Click on for instance 'Hylke Postma'
  3. It links to the user 'Matthias Eisenlohr'
