Show all test steps in progress formatter (#3029)
The progress formatter historically has only ever rendered pickle steps. Once hooks were added to Cucumber the progress formatter would also include failed hooks, but no other hooks. This seems rather inconsistent. As hooks also take time to execute and may fail it makes sense to include them in the progress bar. Not entirely coincidentally, this also makes it easier to use Cucumber messages.
