Fix FOREACH_SCENE_COLLECTION/FOREACH_SCENE_OBJECT for nested collections
This fixes any function that relied on these iterators such as:
* Outliner Same Type
* Metaballs
* scene.objects
We were not considering the collections when there was collections nested
to the collections nested to the master collection.
It includes a unittest.
