I had tests that failed without it.  E.g. An edition was created with some edition organisations and then the edition organisation was separately manipulated to make it featured, then a new draft is created from the edition and the new draft didn't inherit the featured attributes of the association ('cos the instance loaded in the edition hadn't refreshed from the db to contain them).

This isn't likely to happen in the wild so maybe I should just make the edition in the test do the reload.
