The results of the hook in PageRepository->enableFields and of
PageRepository->getMultipleGroupsWhereClause may be different,
depending on the Context state for usergroups.
In TYPO3 v9, PageRepository was also used when resolving pages
during Routing (where there is no user / group resolved yet),
which is why we may face different states of usergroups in PageRepository.
