fix: faces a sheet fold moves keep their names (#535) (#585)

Faces that a sheet fold or unfold moves keep their names: points on a moved panel are taken back through the panel they lie on to where the sheet held them before the feature, and named from the faces there. Un-ignores the #535 regression test. Fixes #535.
