JSON deserialization: Empty objects accepted where arrays are expected

[otto-ifak]

In JSON deserialization, the SDK accepts empty objects where an array is expected. Eg. keys in the following:

{
   "modelType": "Property",
   "valueId": {
        "type": "ModelReference",
         "keys": {}
      }
}

I guess this is caused by code like the following:

        if not isinstance(jsonable, collections.abc.Iterable):
            raise DeserializationException(
                f"Expected an iterable, but got: {type(jsonable)}"
            )

(Dict implements Iterable)
