    Using GtkTreeRowReference instead of a string path.
    
    - When the user selects another account and has pending changes to the
      currently selected account, we need to keed track of the destination
      row. Instead of saving that information as the string representation
      of a GtkTreePath, we now use a GtkTreeRowReference.
