Fix emoji thumbnail generation to prevent grayscale pngs.

Browse source 
Same problem that we ran into previously with the emoji font--
imagemagick takes RGBA that contain only grayscale and converts
to grayscale with alpha, but although it can display these ok,
chrome can't.  So force it to generate RGBA output.
