Only update one autocomplete field after successful node creation Before the patch, the title of the newly created node would appear in every inputs of the field, which wasn't all that usefull. The code now only updates one field, and /tries/ to be smart when making the choice of which one to update: if there's an empty field, we'll put the value there. If there isn't, then we'll use the first one. Ideally, the code would check if the field is configured for "Unlimited" values, and if it is, try to add a new input instead of blindly overwritting potentially valuable user input.
