I always just interpreted that scene as "Well okay I'll do this thing for you if you get this celebrity you know to appear at my niece's birthday party", because who wouldn't want Iron Man (or just Robert Downey Jr, which ever) to appear at their party? I don't think it's really foreshadowing anything, it's just a silly little throwaway joke.

That said, I am keen to see what they do with Ultron in Avengers 2. My biggest concern so far is they're not really doing anything to build up to his introduction. The post-credits scene of Iron Man 3 would have been a perfect place to sow the first seeds as it were, but alas it wasn't meant to be.
