title: Problems upgrading to Spring Data Neo4j 4.0.0
body: <p>I'm trying to upgrade a project to Spring Data Neo4j 4.0.0 and I'm facing two problems :</p>
  <ol>
  <li>The &quot;spring-data-neo4j-rest&quot; package is missing at MvnRepository (<a href="http://mvnrepository.com/artifact/org.springframework.data/spring-data-neo4j-rest/4.0.0.RELEASE" rel="nofollow noreferrer">spring-data-neo4j-rest-4.0.0.jar</a> returns 404 error). Does the package still exist and should be there, or should I just delete the dependency from my pom.xml?</li>
  <li>I've got the following error : <code>The method fetch(Set&lt;...&gt;) is undefined for the type Neo4jOperations</code> in all my DAOs. The method was used to initialize collections of lazily loaded nodes. How can I initialize a node's collections?</li>
  </ol>
  <p>Thanks!</p>
