Document the need to remove the @Ignore from other tests in each exercise

[duckpuppy]

In #30, each test after the first was @Ignored with the idea that the student would remove that annotation from the remaining tests. In #30 (comment), it was mentioned that a future PR was inbound to address documenting that. I began the Kotlin track yesterday (5/17/2018) and nowhere in the TUTORIAL.md or README.md for hello-world was there a mention of removing them. I didn't even notice skipped tests until the second lesson, and only because I'm a seasoned developer familiar with testing frameworks did I think to investigate the test file and remove them.

@jtigger did that in #31, but it's indeed no longer there. Removed by 119d9b1 in #111.

@duckpuppy Do you know if this is still an issue?

@duckpuppy Do you know if this is still an issue?

Hello, this is still an issue as reported in #300, #301 (and other tests)

[mikegehard]

Thanks @blueglyph.

I'll take a look at the commits referenced above and back in some language around the @ignore annotations.

I believe this is at least partially addressed by #296 so I'm closing.

If there is more work to be done, please file another issue or open a pull request with specifics.

Thanks!
