Adds two undocumented v: variables: _null_list and _null_dict because I do not know a reproducible way to get such lists (though I think I heard about this) and dictionaries (do not remember hearing about them). NULL strings are obtained using $XXX_UNEXISTENT_VAR_XXX. Fixes crash in json_encode($XXX_UNEXISTENT_VAR_XXX). Other added tests worked fine before this commit.
