Fix Drupal.Commenting.FunctionComment.Missing in module tests

Linting passed, so setting for review.

Reviewed the MR. Changes look good to me. Also ignoring the sniff in files using testN() seems to be fine.

The Needs Review Queue Bot → tested this issue. It fails the Drupal core commit checks. Therefore, this issue status is now "Needs work".

This does not mean that the patch necessarily needs to be re-rolled or the MR rebased. Read the Issue Summary, the issue tags and the latest discussion here to determine what needs to be done.

Consult the Drupal Contributor Guide → to find step-by-step guides for working with issues.

Time to get some reviews here.

Re-ran test failures and they were all random.
