This fixes the problem, but I think it might be better to add something
like `def producedAttributes: AttributeSet = AttributeSet` to `QueryPlan`.
This can be automatically subtracted from `missingInput` and nodes that produce
attributes can override this function. I think that will be clearer. What do
you think?
