Pedro J. Estébanez 922cf9fbb0 Fix crash on node duplication 
That happened when an instanced scene was being duplicated while it also contained nodes added to it in the scene holding the instance.

Plus:
- Add comments about the logic behind all this.
- Move the null guard to where it can protect the most, but consider it a runtime error rather that a situation we expect.

Fixes #13282.
