System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: Quadro P4000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 418.96

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-01 06:11, hash: c74626c54f
Worked: Blender 2.79b and before

Short description of error
When creating new Render Layer nodes in the Compositor, Blender no longer increases the user count of the scene datablock, leaving Blender in an unstable state. When saving and reloading the scene, the user count has magically increased and is correct. Also, on a side note, in the 3D View header, the user count button becomes clickable. In 2.79 it is disabled, which is what it should be.

Exact steps for others to reproduce the error

Create a new scene, check use nodes in the Compositor
Create a new Render Layer from the Add menu
The user count of the scene datablock is still at 1
Save the scene, and reload it
The user count increased to 2

Some images to illustrate:

fresh scene

added Render Layer node

after save and reload

fresh scene in 2.79b

after adding Render Layer node. No reload required.
