[minor] One hint on the last lesson gives an error

[moT01]

If I have exactly one hint on the last lesson, I get en error:

It's only on the last lesson. If I don't have any hints, it works - if I have more than one hint, it works.

This is very minor, I can always find another hint to add.

I tried to replicate this issue here: coderoad/coderoad-cli#77

But can't seem to reproduce it. I looked at the learn-git-by-building-an-sql-reference-object example for a reference.

Any idea what I might be missing?

This appears to be fixed. I had an older version of the CLI, updating it no longer gives the error.
