Add an ISBN Verifier test case for short ISBN

[jgomo3]

If your code verify the isbn length to be only less than or equal to 10, it will accept some ISBN with less than 10 digits which still satisfy other rules, being "00" a case which could be considered ISBN by some "almost correct" solutions missing this consideration.

I.e: http://exercism.io/submissions/f2fac1e79bf441e08afecd196ec0a442

Thanks for the PR @jgomo3 ! I'm happy to add this as a test case here, I wonder if you'd be open to making a PR to the shared test cases for all exercism tracks here https://github.com/exercism/problem-specifications/blob/master/exercises/isbn-verifier/canonical-data.json as well?
