stats.py doesn't work with images imported with omero-cli-zarr

[dominikl]

First example for such an import was idr0173. Imported directly from URL, without METADATA.ome.xml. stats.py script doesn't produce any output:

(venv3) [dlindner@prod130-omeroreadwrite metadata]$ python idr-utils/scripts/stats.py --release prod130 idr0173-breiter-alphasynuclein
Using session for demo@localhost:4064. Idle timeout: 10 min. Current group: Public

I guess that's probably because there are no files/filesets in the DB.
