shareable: Reset non-updated-count at ReplacePixels

Browse Source 
Before this change, ReplacePixels didn't affect the non-updated-count,
and an image using ReplacePixels tended to be on a shared image.
This was OK, but as lazy pixel loading is going to be introduced,
ReplacePixels also needs to reset the count.

Updates #1414
