When moving a linked collection, we seem to only receive a depsgraph update
for an empty object so the Blender synchronization cannot discriminate it
and tag the object(s) (light or geometry) for an update through
id_map.set_recalc.
This missing transform update only affects lights since we do not check
manually if the transformations were modified like we do for objects.
To fix this, add a check to see if the transformation is different provided
that a light was already created.
