Invalid output of tojson() for Set and Map objects

Info

For legacy reasons tojson() output does not produce valid JSON, but some serialization of objects that is expected to be evaluable. Currently, tojson(new Set([1, 2])) returns [1, 2], which evaluates to Array, but it should rather be "new Set([1, 2])". The same is with Map instances.
