When using command buffers, shadowmaps are delayed when fetching shadow projection parameters.

Steps for reproduction:
1) Download the project and open the scene `11. Shadow casting (PREVIEW)`
2) Enter into play mode
3) Hold left mouse button and drag it to rotate around the scene
4) Notice that shadowmaps are delayed
5) Observe the bug

Notes:
- Shadow projection parameters are fetched in Assets\8i\core\common\scripts\rendering\HvrShadowMapParamSniffer.cs script
- Not a regression, the behaviour is the same across all Unity versions (including the versions Command Buffers are introduced)
- A detailed document to explain what kind of approach is followed is added to the comments
