[test] drop forsaken windmill test (Closes 2535376) * not run since multiple years * windmill itself is in poor shape not even packaged in Debian.

[predicates] keep making `yes` predicate importable from cubicweb (closes #2790319) The `yes` predicate was moved out in CubicWeb 3.15 but it should have remained importable from the cubicweb.predicates module, for bw compat reasons and also because logilab.common.registry is an implementation detail.
