Missed passing metadata=self.metadata in Option.process

[thewhaleking]

I'm actually not quite sure how to add a test for this. But it resolves decoding an Extrinsic with the data

ScaleBytes("0x85028400d43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d01d8a8c7ab390badc106832ccb721d1acea313335db6c0bcd816c160a1c2784e3f41f503d08f321ab66aa3401e941737ebad721ea3db5c7bee784b87f9130fcc8e009c00001b000700c817a80402286bee0700902f50099228010001073b8eaf04151687736326c9fea17e25fc5287613693c912909cb226aa4794f26a4800")

given this metadata:
metadata.txt

@arjanz pls take a look this PR

Confirmed, I created a unit test with data mentioned above and the patch fixed decoding of the extrinsic:

    def test_encode_with_bittensor_metadata(self):
        metadata_fixture_dict = load_type_registry_file(
            os.path.join(os.path.dirname(__file__), 'fixtures', 'metadata_hex.json')
        )

        metadata_decoder = RuntimeConfiguration().create_scale_object(
            'MetadataVersioned', data=ScaleBytes(metadata_fixture_dict["bittensor_test"])
        )

        metadata_decoder.decode()

        runtime_config = RuntimeConfigurationObject(implements_scale_info=True)
        runtime_config.update_type_registry(load_type_registry_preset("core"))
        runtime_config.add_portable_registry(metadata_decoder)

        extrinsic = runtime_config.create_scale_object(
            "Extrinsic",
            data=ScaleBytes("0x85028400d43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d01d8a8c7ab390badc106832ccb721d1acea313335db6c0bcd816c160a1c2784e3f41f503d08f321ab66aa3401e941737ebad721ea3db5c7bee784b87f9130fcc8e009c00001b000700c817a80402286bee0700902f50099228010001073b8eaf04151687736326c9fea17e25fc5287613693c912909cb226aa4794f26a4800"),
            metadata=metadata_decoder
        )

        extrinsic.decode()

        self.assertIsNotNone(extrinsic.value)
