Title: Better message if user passes URL w/ no scheme

If it looks close to a URL, let's display a more informative error message
prompting them to add a scheme. If it's not close to a URL we just tell them
the URL is invalid.

Also add a README to the tests directory.

Tests:
No unit tests as only the error message is changing, not the validation logic.
