Fix doors unable to push single item into storeboxes

The special case of trying to push a single item into a storebox
is an overlap between the item catapult and the place-node recipe.
Change the priority order so the catapult check is done first.
This is not expected to cause problems in other cases because in
those, the presence of a "backstop" node causes them not to overlap.
