ES create_mapping() fails for graphs that used the concept->reference node migration

[johnatawnclementawn]

1. Create an example model with n >=1 concept nodes
2. Ensure collections used in those concept nodes have been migrated to controlled lists (migrate_collections_to_controlled_lists)
3. Use migrate_concept_nodes_to_reference_datatype to migrate those nodes to the reference datatype
4. Export the graph through the graph designer
5. Delete the graph
6. Use the graph designer UI to import the graph & observe error:

note: this does not happen for graphs that have reference datatype nodes initially configured as reference nodes.
