metadata-search: Return swh-search even when missing from idx_storage.origin_intrinsic_metadata
This is needed, because swh-search may now return results based on extrinsic metadata, in addition to intrinsic metadata.
I do not want to query idx_storage.origin_extrinsic_metadata here, because it is not clear how to merge with the existing data structure.
Additionally, I do not think anyone relies on the metadata returned by this endpoint because it is undocumented and rather inflexible. Instead, I would like to deprecate returning metadata from this endpoint altogether, as there is a more appropriate endpoint to get metadata once you have the origin URL.
Resolves swh-search#4599 (closed).
