Cleanup: Don't store hash in picture struct in learnHash()

learnHash() is called either on a local picture structure
[DiveListView::loadImageFromURL()] or on a cloned picture structure
[ImageDownloader::saveImage()]. In neither case the picture structure
is passed to the frontend. Therefore, storing the new hash in the
picture struct is not necessary.
