explicit_generic_args_with_impl_trait: fix min expected number of generics Fixes rust-lang#87718 The problem was that `synth_type_param_count` was already subtracted from `named_type_param_count`, so this ended up being subtracted again. This caused `expected_min` to overflow, and ultimately resulting in weird and wrong behaviour. I've also added another test not present in the original issue but caused by the same bug.
