When graphics jobs are enabled ambient calculation seems to be ignored

Severity: 3Workaround is possible

When graphics jobs are enabled ambient calculation seems to be ignored.

To reproduce:

1. Open project.
2. Enable Graphics jobs in Player settings.
3. Build x64 Windows Build.
4. Launch the build.

Observe the cube. (enabled.png)

5. Disable Graphics jobs.
6. Build x64 Windows Build.
7. Launch the build.

Observe the cube. (disabled.png)

Expected results: both cubes look the same.
Actual results: firs cube have a much stronger shadow.

Important notes:

The ambient calculation is embedded in a custom Deferred Reflection shader (Kite-DeferredReflections.shader)
It uses ShadeSH9() to calculate the ambient.

5.4 handles shaders differently compared to 5.5

Apparently ShadeSH9() returns black if Graphics Jobs are enabled.

Reproduces with: 5.5.0f3; 5.5.0p1; 5.5.0p2: 5.6.0b3;
