patch 8.0.1164: changing StatusLine highlight does not always work
Problem: Changing StatusLine highlight while evaluating 'statusline' may
not change the status line color.
Solution: When changing highlighting while redrawing don't cause another
redraw. (suggested by Ozaki Kiichi, closes #2171, closes #2120)
