is https://github.com/ome/omero-install/blob/v5.2.3/linux/step01_centos7_deps.sh not enough?

Start by reviewing linux/step01_centos7_deps.sh and the traceback locations in omeroweb/webgateway/views.py, especially object_table_query and _table_query. Reproduce the missing Tables error and compare the setup with the reported Not yet initialized failure; the issue is done when the dependency setup allows the table query to initialize successfully.
