+ * Tests that setting cluster to immutable after cluster is changed to big works.
+ * Init request adds immutable cluster to database. 
+ * Modify request checks that it is immutable.
+ * The tests requires that small cluster is converted to big and that the cluster is fetched from the server.
+ * 
+ * There was a bug in ProCoreServer which caused changes in immutable state to be discarded when small cluster was converted to big before setting immutable state.
+ * Refs #4688 (https://www.simantics.org/redmine/issues/4688). Fixes https://www.simulationsite.net/redmine/issues/8866.
