cubicweb-securityprofile #2496280 user/group coherency issue wrt. ldap-driven and local-admin driven changes [open]

When everything is treated from the LDAP source, it works perfectly fine.

But if someone modifies (by hand) the relation between a user and the groups it belongs to, we have a inconsistency between the groups and the security profiles associated to the user that will be not fixed with the automatic synchronisation.
