    migrate_extrinsic_metadata: guess PyPI origins.
    
    This works by guessing the package name from the original_artifact data,
    then building an origin that would match the package name, then filtering
    checking if the revision can be reached from it.

    migrate_extrinsic_metadata.test_pypi: use the in-memory storage instead of mocks

    migrate_extrinsic_metadata.test_debian: use the in-memory storage instead of mocks
    
    in tests that need to read in the storage.
    
    Using mocks just makes it more complicated, and we decided not to do that
    a while ago.
