Add FirstLoginListener to accept shares upon first ldap user login

Trigger OCP\Group\Events\UserAddedEvent on first ldap user login for all his groups, to avoid having to wait on the background job before shares get accepted.

This does not work, the listener never gets called on neither of the 2 events according to the log… I do not understand the problem.

Also, I’m wondering if this solution is enough, because it will only work for new users, not when adding an existing user to a group.
But checking if Nextcloud is aware of group membership on any login, or each time the group membership is queried is way too expensive performance wise I suspect.

[notes for myself]

The idea is now to change the format of data stored by the update group background job so that we can easily search in it if a user/group association was already detected, and at login we browse known groups of the user, and if association is missing we announce it with a UserAddedEvent.
