Temporary fix for --preAbandonGpuContext bug

In this instance what is going wrong is:
  the context gets abandoned
  SkCanvas tries to create a new SkGpuDevice (which fails)
  if then creates a bitmap device
  it then attempts to draw the abandoned GrTexture (behind the old SkGpuDevice into the new bitmap device with an image filter
  b.c. some image filters still switch their behavior based on the presence of a texture bad stuff happens

This used to be resolved by the new bitmap device getting forced down the bitmap path and then failing when it attempted to readback the GrTexture.
