:warning: This is has the same (upmerge) code as https://github.com/Normation/rudder/pull/5953, it will likely need to be closed

In 8.2 we need to recompute the hierarchy of group and node properties after having updated a group property, this has to be added in the setup of the test. Also, to make the tests still pass, some fields needs to be added to the data model of the error : standard attributes from properties (description, provider, inheritmode), and passed around up to the JSON serializers
