Renames the data product in test_granule_publish

The granule in test_granule_publish isn't formed for transforms or to be
ingested but because another test still has transforms running on the
services container this granule gets routed to those processes and
causes problems, by renaming the data product to something unique the
data will never go somwhere it does not belong.
