Fix T92149: Crash in delete geometry node after curve fill node

There was only a check for the component but not for if it was empty.
Because the curve fill node produces an empty curve component, a
nullptr was read, causing a crash. Generally nodes shouldn't produce
empty components, but currently we cannot rely on that fact.
