- opf openproject: fixed in 17.0.2

This functionality should only be possible for users of the application, but they were not supposed to be able to lock application administrators. Due to a missing permission check this logic was not enforced. The problem was fixed in OpenProject 17.0.2The problem was fixed in OpenProject 17.0.2.
