Seeing the trait definition doesn't help with implementation not general enough errors, so don't make the error message larger to show it.
If we have a cause containing `ValuePairs::PolyTraitRefs` but neither TraitRef has any escaping bound regions then we report the same error as for `ValuePairs::TraitRefs`.
