  @param path
  The path (starting with "/") to the file or folder (see {@link DbxPathV1}).
  
  @param includeMediaInfo
  If {@code true}, then if the return value is a {@link DbxEntry.File}, it might have
  its {@code photoInfo} and {@code mediaInfo} fields filled in.
  
  @return If there is no file or folder at the given path, return {@code null}.
  Otherwise, return the metadata for that path and the metadata for all its immediate
  children (if it's a folder).
