I was going to say a hard no on that one, but thinking of it, it's a bit trickier than that. We can have two interpretations of that now, which are:

a) Wish!Emma sang because she was never torn apart from her people and "the song" remained with her, not being stripped away by the harsher upbringing she actually had. That could work as an in-universe explanation, but not as much as planting in cinematic language because –

b) Wish!Emma was egregiously out of character. All of her actions are nothing like the real Emma and the singing was included in that and specifically framed in her later conversation with Regina as something she wouldn't normally do.

So I'm still going with no, that wasn't foreshadowing, that was yet another symptom of how much Wish!Emma was unlike real Emma.
