Fetching updated packages failed: Missing non-optional field 'score' of type 'DbPackageStats' (DefaultPolicy(T)).

[timotheecour]

@s-ludwig fix for https://github.com/dlang/dub-registry/issues/282#issuecomment-367665542 still fails with: ./dub-registry --mirror=https://code.dlang.org object.Exception@../../../../.dub/packages/vibe-d-0.8.3-alpha.4/vibe-d/mongodb/vibe/db/mongo/collection.d(323): Aggregate command failed: The 'cursor' option is required, except for aggregate with the explain argument

however it makes some progress (finally!) if i replace dub.selections.json with:

"vibe-d": {"path":"../../../D/vibe.d"}

however it gives another error in this case:

This is due to the registry not being updated yet. Two ways to fix this for now:

1) optional

dub add-local should work too. Anyhow, let's bump the dependencies:
