Move test crates into a "testing" folder and add a ui (trybuild) test and ui-test helpers (#567)

* move test crates into a testing folder and add a ui test and helpers * undo wee mixup with another PR * cargo fmt * clippy * tidy ui-tests a little * test different DispatchError types * refactor dispatch error stuff * name ui tests * duff => useless * align versions and cargo fmt
