ES: update permission spec table

Remove impossible cases due to private project's features can only be
private or disabled.

Fix spec due to sidekiq indexing not triggered.

Update guest use cases: some features has additional constraint that
"Guest users are able to perform action on public/internal projects,
but not private ones."
