Updates are not synchronized with Keycloak

• Mandates: Mandates should be synced with Keycloak, but it doesn't seem to work. Investigate!
• First and last names: when creating users, we get their first and last names from Keycloak. Then we store this information in our database and allow the user to edit the information. We should ensure the edits are sent to Keycloak as well so that the information stays up-to-date.

Mandates seems to work locally with sandbox. Added so it updates name whenever user changes their name (#518).

Syncing mandates seem to be broken still, no one in the Teknikfokus project group got their mandate synced

It was not a problem on our side! The problem was groups being incorrectly nested in keycloak, for example dsek.teknik.projgr.mdlm was in the same subgroup as dsek.teknik.projgr, instead of being a subgroup of it
