POST /api/v4/projects/:id/statuses/:sha  {"name": "check", "state": "success"}

THEN pipeline is updated: failed job disappear and a new success external status is created

The merge request becomes mergeable and pipeline result representation shows a failed but empty badge

after_mr

EXPECTED jobs status shall not be overwritable with the commit statuses API. Only External Status shall be.
