Starting render SPP 1 issue

When starting the render, if you disable the albedo map, and render the standard scene, chunky starts by rendering the first SPP of the normal map, but immediately after renders the path tracing scene.
After that, if you render the scene without the albedo map, Chunky starts by rendering the first SPP twice, and then it continues normally.
If you reenable the albedo map, chunky starts by rendering the first SPP of the path tracing render, before rendering the normal maps. Afterwards, if you start the render, it renders the first SPP of the normal map twice before proceeding.

No source file, test, or entry point is named. Reproduce the render sequence with the albedo map disabled and reenabled, using the standard scene, and compare the order of the normal-map and path-tracing SPP renders across consecutive starts. Done means each render begins with the correct first SPP exactly once.
