Repository pattern logging is broken

[iluwatar]

While running the Repository pattern example I noticed that logging doesn't work. It should log some things to standard output, see for example here https://github.com/iluwatar/java-design-patterns/blob/master/repository/src/main/java/com/iluwatar/repository/App.java#L74
