Remove unnecessary check from Groups#AutocompleteService
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/8632/diffs introduced an unnecessary check when performing auto complete for milestones in epics.
It checks if user can read current group parents which is not needed. When user can read
group he also can read its predecessors.
TODO
- Remove
ParentGroupsFinder
if it is not being used on another place yet and usegroup.self_and_ancestors
.
