Issue #2041 Follow-up - Remove opacity check from original patch.

Browse source 
Per Issue #2033 we don't support expanding RGB to RGBA yet, so this opacity
 check will always return RGBX, which makes images with transparent backgrounds
 show up with a black background instead. Feel free to readd once we backport
 Mozilla bug 1551088.
