reload(atIndex:) should take into account videoURL for video items

[themoonlitknight]

In a common scenario where GalleryViewController is presented with a video item having a preview image but without the actual video data, which will be fetched while the gallery is visible, I would expect that a call to reload(atIndex:) would try to load the videoURL. Instead it reloads only the preview image.

I can't see a clean solution/workaround to that.
