Repro steps:
1) Open the project and [Moonshine].scene
2) Notice the volumetric lighting in the scene
3) Play and try moving around fast with arrow keys
4) Notice the stuttering of vol. ligthing which is caused by delayed shadowmap matrices
5) Enable Spot Light object
6) Notice the volumetric light disappears

Reproduced on: 5.4.0b16; 5.4.0b13
Couldn't setup the project to fully work on earlier versions

Expected behaviour: Shadowmap matrices are set before LightEvent.AfterShadowMap trigger
