Fix large delta on next frame when turning t_simulationTickDeltaOverride off. (#5716)

Browse Source 
This was due to incorrectly setting m_lastSimulationTickTimeUs when t_simulationTickDeltaOverride was enabled to the override.
m_lastSimulationTickTimeUs is now always set to the current time so the delta calculation will always be correct.
