[eog] EogJobSave: Do not unref current image pointer at dispose

    EogJobSave: Do not unref current image pointer at dispose
    
    The pointer was not ref'd before as it is only an iterator into
    the larger image list held by the job. So, simply make sure to unset
    it before clearing the image list.
    
    Fixes #154.
