refactor: CasesOnApp.refineThrough can return a lambda, not an open term (#2974) 
which also removes an error condition at the use site.

While I am at it, I rename a parameter in `GuessLex` that I forgot to
rename earlier.

The effect will be user-visible (in obscure corner cases) with #2960, so
I’ll have the test there.

A few places would benefit from a `lambdaTelescopeBounded` that
garantees the result has the right length (eta-expanding when
necessary). I’ll look into that separately, and left TODOs here.
