    migrate_extrinsic_metadata.test_pypi: use the in-memory storage instead of mocks
    
    in a future commit, migrating pypi revisions will become more interactive with
    the storage, so it's easier to have a real one instead of a mock.

    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.

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