Judge a group's controller by itself with the validator it vendors, and copy nothing of mesh-host's (issue 1391, 3 of 3)

judgeFromTheGroup copies nothing into the judge's vendor tree: a mesh-host member whose tree holds no validate/ does not fail the judge, and the verdict names the validator as mesh-sdk's at the pin of the controller that judges. replaceGoFiles and its test are gone.
