Issue #22623 demonstrated another lacuna in the implementation
of wrinkle (BS3) in Note [The binder-swap substitution] in
the occurrence analyser.
I was failing to add TyVar lambda binders using
addInScope/addOneInScope and that led to a totally bogus binder-swap
transformation.
Very easy to fix.

The old assertion saw that a constraint ct could rewrite itself
