bproc.clean_up() resets render device to CPU

[simon-lgb]

Describe the issue

After calling bproc.clean_up(), all custom properties of the scene are deleted. This also affects the default settings setup in bproc.init() like the rendering device. In my opinion, this is unexpected behavior.

Minimal code example

import blenderproc as bproc
import bpy

bproc.init()

print(bpy.context.scene.cycles.device)

bproc.clean_up()

print(bpy.context.scene.cycles.device)

Files required to run the code

No response

Expected behavior

I would expect the initial setup of init to be kept intact or repeated where necessary.

BlenderProc version

2.7.1
