function EntityReferenceAutoCreateTest::testAutoCreatedNodeNewNodePreview

Test previewing autocreated node in a new node is not flagged as recursion.

Entity render recursion is prevented by pushing/popping entities being rendered on to a stack keyed by a string made up of the entity type ID, entity ID, and the view mode. In the case of new entities, the entity ID is NULL, so this test checks that unique identifiers are used in the stack keys for new entities to prevent false positive recursion protection.
