Fix T86172: tag relations update when pasting nodes
Pasting nodes can create new id relations, because nodes can reference IDs.
Therefore the depsgraph has to be updated when nodes are pasted.
We could somehow check if the pasted nodes referenced IDs, but I'm not sure
if this complexity is worth it.
