ViewRender was removed, which means we can't get the render engine for files saved in 2.8. We assume that any files saved in 2.8 were intended to use Eevee and set the engine to that. A fix included with this is that .blend thumbails now draw with Clay mode, and never Eevee or Cycles. These were drawn with solid mode in 2.7, and should be very fast and not e.g. load heavy image textures. Differential Revision: https://developer.blender.org/D3156
