patch 9.1.1011: popupmenu internal error with some abbr in completion item

Browse Source 
Problem:  Popup menu internal error with some abbr in completion item.
Solution: Don't compute attributes when there is no corresponding text.
          Reduce indent in pum_redraw() while at it (zeertzjq).

fixes: #16427
closes: #16435
