Unity crashes on play when probes settings are changed in OnWillRenderObject() with:
> Unity.exe!ReflectionProbe::GetCachedRenderer(void) Unknown
Unity.exe!ReflectionProbeJob::Run(void) Unknown

Reproduction steps:
1. Open project attached(Probes repro).
2. Open scene "Main".
3. Press play.

Expected result: Unity will enter play mode.
Actual result: Unity crashes.

Notes: In 5.5.0f3, this crash is reproduced just by changing probe mode to Realtime. In 5.5.1f1 and 5.6.0b5 you also need to change probe refreshMode to EveryFrame.
This problem does not appear if function is called in Update.
For more information look at OceanReflection.cs.

Reproduced on: 5.4.0f3, 5.5.0f3, 5.5.1f1, 5.6.0b5.
