TypeError: Cannot read property 'tick' of undefined when not using -p

Using asciidoc-link-check@1.0.13:

/tmp/node_modules/asciidoc-link-check/index.js:39
                bar.tick();
                    ^

which ultimately fails the run.

This is a problem because it means you have to enable progress when running CI where it messes up the update.
