Convert constant to memoizing accessor. #4176.

The definition of `ORDER` indirectly referenced the code list cache.
This led to some situations where COMMUNICATION_RANK_CL1 was cached
as a non-list before it could be loaded into the database.

Regenerate pg_dump files. #4143, #4149, #4159

* Ran `rake mdes:code_lists_all`
* New versions of pg_dump files
* YAML files were unaffected
* I believe this to be the root of the issue for each of #4143, #4149
  and #4159
