A Blueprint created from Actors in the level does not preserve the relationship (hierarchy and transforms) of both components.

Reproduced in 4.8.3 binary, 4.9 Release (//depot/UE4-Releases/4.9/Promotable-CL-2650750), and Main (//depot/UE4/Promotable-CL-2649225)

Steps to Reproduce

1. Open any project
2. Drag two Cubes into the level (Modes > Basic)
3. Drag the second cube in the World Outliner onto the first cube to make it a child of the first cube
4. Rotate the first cube
5. Select both cubes
6. Blueprints (in the Menu bar) > Convert Selected Components to Blueprint Class

A new Blueprint is created but the hierarchy of actors is not recreated, and the second cube is translated to a new location

The new Blueprint maintains the relationship (hierarchy and transforms) of both components
