LPS-34896 Fix NPE when adding new sites
LPS-34970 - Fix the test for including Placeholder plugin on the page
LPS-18616 Logging is being removed because it takes too much effort to calculate if we should print out the log message or not. The state of these are playing a role in this picture: autoArticleId, existingArticle, portletDataContext.isDataStrategyMirror() and they have to be checked with different permutations. Also the pattern is to not log anything if we update it during the import.
