With an upstream outside the group, the placeholder of an
all_done_min_one_success task decided the whole task from that upstream
alone. A none_failed_min_one_success task failed every index when one
upstream index failed.

For both rules, the placeholder now hands the decision to the expanded
instances once an in-group upstream has expanded. Each index is then
judged by its own upstreams.
(cherry picked from commit b43705c)
