Treat comment as non-empty block body

[koral--]

If block is empty intentionally it can contain a comment. Here is how sonar-java plugin handles this: https://github.com/SonarSource/sonar-java/blob/321e3d4994d3134f29d58ab23b96d1e46d95f8f9/java-checks/src/main/java/org/sonar/java/checks/EmptyBlockCheck.java#L62

Seems reasonable to me.

Please update the test case and use the rule directly instead of copying the hasCommentInside code :)

Done.
