Copied analysis result not saving to cloud service

[coruscating]

When experiment data is copied and then saved, everything saves to the cloud service except analysis results:

data2 = exp_data.copy()
data2.save()

So data2.analysis_results() is correct, but if data2 is loaded from the cloud service, its analysis_results() is empty.

This does not seem to be caused by the analysis result refactor because 0.5 has the same issue.
