Support storing job config history in folders
Talking about ItemGroup (an internal API) in the UI is needlessly confusing.
Recurse into folders looking for job configuration history.
Do not record two events on the same job with the same timestamp; wait a moment so distinct history entries are created.
Race condition observed to affect folder renames, which are apparently just quicker than job renames.
Test was actually written assuming race condition. In reality there is a create and then a change.
