Werk #6552: Role changes now create change entries on central site

Changes to the roles in WATO triggered change entries for remote sites where the user login is allowed but were missing to add change entries for the central site.

This is relevant for the "discard changes" feature. In case such a role change is made by one user and a another, less privileged user, tries to discards his changes it would be possible to discard the changes of the first user in case no change entry is created.
