Fixed the comment in the POM

The comment in the POM wrongly describes the tested scenario. I guess this was due to a copy and paste from another IT, https://github.com/apache/maven-compiler-plugin/blob/master/src/it/mcompiler-21_methodname-change/pom.xml
diff --git a/src/it/mcompiler-21_class-remove/pom.xml b/src/it/mcompiler-21_class-remove/pom.xml
