On exercise "navigation-computer" - tests are passing even when last task is not implemented

[Norbiox]

I've been resolving the task in the Exercism editor. I got to the third (and last) task, but when I run tests before even removing raise statement from the method, all tests passed and I'm able to submit.

Yes, I opened a pr earlier this evening, I am hoping for a fix to be available tomorrow.
