"fishy" `skip_binder` actually ignoring bound variables

[oli-obk]

    An `expect` there actually does panic for the `src/test/ui/generator/resume-arg-late-bound.rs` test.

I only moved this code between the files, the same comment and code pattern exists as well for normal closures:

rust/compiler/rustc_trait_selection/src/traits/select/mod.rs

Line 2290 in e221616

// (1) Feels icky to skip the binder here, but OTOH we know

I couldn't repro this failure, maybe @Swatinem was doing .no_bound_vars().self_ty() instead of .self_ty().no_bound_vars()? The ordering is important here.

I believe I did, yes.
