OGM-522 Prepare Neo4j queries at startup
OGM-522 Avoid the use of CypherCRUD

  CypherCRUD is responsible for the creation of queries that are going
  to be executed on Neo4j. Since queries are now created at startup we
  don't need to use it anymore.

  This patch will remove the dependency of CypherCRUD from the existing
  classes.
