[zorg] Delete two unused functions from UnifiedTreeBuilder

[gkistanova]

These are unused yet and there for purpose.
Do these cause any problem for you? If so, could you elaborate, please?

[Hahnfeld]

No, they don't cause me any trouble directly. I just wanted to clean up a bit and remove some dead code as it's currently quite confusing which build factories get used.
