Flask application with demosite data and with database isolation: db
transactions performed during the tests are not persisted into the db,

Note: creating an isolated app without the demosite is challenging,
see: https://its.cern.ch/jira/browse/INSPIR-425

and the `isolated_app` fixture should not matter.
Some work to investigate that was done here:
