Fix config for SafetyDB importer

The migration that adds the SafetyDB importer used the URL of the git
repository. However the importer is not actually based on GitDataSource,
since the repository only contains a single file with all security data,
so there is no advantage over just downloading the current version from
master via HTTPS.
