Fix Search-by-image crash when given a nil image/data

My thought was that ResizedImageForSearchByImage should be fine with an
empty image. If, on iOS, it's passed a non-empty image with no UIImage
representation, that will still crash, but is probably ok (although if
that's what DCHECK should be used for, let me know).
