When running versioning for the Glare node, the code assumes the ID
given by the iterator belongs to the scene containing the node tree. But
this might not be the case, as the Glare node might be inside a node
group, in that case, the ID will be the node tree itself.
To fix this, recursively go over the node trees starting from the scene,
passing the scene down all the way. And for node groups not used by any
scene, assume the first scene, since this is better than not doing
versioning.
