Ensure, that our custom code to communicate with the Artifactory backend, behaves identical for missing databases as the code inside audbackend, which returns [] as version when an error is raised. Before, it could happen that an error different from artifactory.ArtifactoryException was raised, and the call to audb.versions() was failing instead of returning [].
