Set render targets before clearing and drawing

[FlightBlaze]

In tutorial 1 i added SetRenderTargets before clearing targets. Without this line of code i get the error: E/Diligent Engine: Diligent Engine: ERROR: Debug assertion failed in PrepareForDraw(), file DeviceContextVkImpl.cpp, line 699: No render pass is active while executing draw command

Can you post the steps to reproduce the problem? The render targets are set by the SampleApp before calling the Render() function, for all tutorials: https://github.com/DiligentGraphics/DiligentSamples/blob/master/SampleBase/src/SampleApp.cpp#L799
