Ref: #1021

[github-actions]

This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

I'm sure the additional tests will make some student solutions fail. But that's OK, I think.

Thank you!

My pleasure.

@mk-mxp : If I do exercism download --force --track=php --exercise=sum-of-multiples, the SumOfMultiplesTest.php is not updated. What's wrong ?

If I remember correctly, you must update the exercise via the website first. Maybe you also need to open the online editor and run the tests once. I don't use the download anymore, so don't rely on it.

OK, that was it: as my solution was broken with the new tests, I had to update via the website first. Thanks!
