3D Environment sky will have wrong brightness when setting background_energy_multiplier

Issue description

I don't think it's a hdr problem or something similar, more like a editor problem. Please read the step below for more info.

Steps to reproduce

You should set some property in editor by yourself, because the problem will disappear when reload the project.

1. Try to set different value to energy_multiplier property in sky's sky_material
2. Run the game, the brightness looks normal
3. Close the game, then set energy_multiplier property back to default
4. Instead we set the background_energy_multiplier property in environment
5. Run the game, the brightness looks not right
6. This problem will disappear when save and close the project and restart it

Not sure if related, but I noticed that if I set a night texture for the sky material, and then reset it to default (empty property) then the sky also gets messed up until I reload the project.

I'm confirming this issue in 4.0.3.rc1. When using a procedural sky, if I change the background_energy_multiplier then run the scene, the running game has different lighting than the editor. If I close the project and reopen, then the lighting is fixed: it is the same in the editor and the running game again.

Changing sky_energy_multiplier in the procedural sky material works as expected.
