Title: Prevent avatars from 'flashing' when refreshing the stream with no changes

When you refresh the stream, and nothing changes, the visible avatars "flash" white and then load the avatar from the NSURLCache. If the image URL doesn't change when you set it, bail instead of swapping the placeholder and the cached image.
