[json] fix json serialization for recent simplejson implementation, and test encoding of entities
as with earlier simplejson implementation, iterencode internal stuff
is a generated function, we can't anymore rely on the _iterencode
overriding trick, so move on by stoping isinstance(Entity, dict).
This is a much heavier change than expected but it was expected
to be done at some point, so let's go that way.
