Make XmlExportables store their export IDs and always obtain a new one, avoiding reuse when an object is allocated at the same heap location as a previous one. This makes the ID system stable enough to be used in the export tests.

+// NB model & dataset IDs in the export tests are incremental,
+// depending on how many have been exported in previous tests - so
+// when adding or removing tests we may occasionally need to update
+// the IDs in other ones
