do not propagate `Err` when determing causal info
In intercrate mode, if we determine that a particular `T: Trait` is unknowable, we sometimes also go and get extra causal information. An errant `?` was causing us to propagate an error found in that process out as if `T: Trait` was not unknowable but rather not provable. This led to an ICE.
