update tests that have changed output

 I’m not sure why these tests have different output now, but they do.
In all cases, the error message that is missing looks like this: “the
trait bound `dyn Trait: Trait` is not satisfied”

My guess is that the error message is going away because object-safety
now involves trait solving, and these extra error messages are no
longer leaking out.
