Title: LPS-30506

Both copyArticle and importArticle will call the validate method. When import article with multiple version we should also check the version since the articleId will be the same always. So I rollback the fix in LPS-22737 to add the fix to the copyArticle method. So now the validate method only check ArticleIdException and check DuplicateArticleIdException in each other's validate method.
