Message Title

The insert order generated by ActionQueue.InsertActionSorter.sort(executables) seems to be wrong:

With "order_inserts=false":
[EntityInsertAction[com.magneto.entities.EntityTreeNode#5000003]
 EntityInsertAction[com.magneto.entities.ContentNode#5000002]
 EntityInsertAction[com.magneto.entities.ReferNode#5000001]
 EntityInsertAction[com.magneto.entities.ContentNode#5000000]]

With "order_inserts=true":
[EntityInsertAction[com.magneto.entities.EntityTreeNode#5000003]
 EntityInsertAction[com.magneto.entities.ContentNode#5000002]
 EntityInsertAction[com.magneto.entities.ContentNode#5000000]
 EntityInsertAction[com.magneto.entities.ReferNode#5000001]]

As can be seen, in the second case, the ContentNode that points to ReferNode gets inserted before ReferNode leading to the FK Violation as thrown:

Caused by: org.h2.jdbc.JdbcBatchUpdateException: Referential integrity constraint violation: "FKOF7VW3LB79R3IQXK1JL523618: PUBLIC.ENTITYTREENODE FOREIGN KEY(LEFTNODE_ID) REFERENCES PUBLIC.ENTITYTREENODE(ID) (5000001)"; SQL statement:
insert into EntityTreeNode (leftNode_id, DTYPE, id) values (?, 'ContentNode', ?) [23506-176]
