cubicweb-vcreview #5230287 do not generate notification for state changes from "outdated" state [validation pending]

messages like:

__internal_manager__ changed status from <outdated> to <en attente de revue> for entity
'[testlib] Optionally print traceback from log file upon subprocess error'

are not very useful from the end-user point of view since this "outdated" state is somehow an implementation detail.
