Fix/graphdb query claim

Dear Denis, I have fixed the query output for test01StoreSelfDescription test in sdstore SelfDescriptionStoreCOmpositeTest. I saw the issue was that we didnt previously handle List class from Neo4j output and hence we decided to return the object instead completely. Also we deprecated the `getDynamicallyAddedCountClauseQuery method from Neo4jGraphStore class as we found this to be not needed because we can get total count of results directly from returned query object. Lastly we replaced the assertion in postGetQueriesReturnSuccessResponse test under QueryController file because the example query returns only 1 result and not 3 for the given cypher query. These are our changes. Please have a look and we will fix based on your feedback. Best Regards Nikhil Acharya
