patch 8.0.1164: changing StatusLine highlight does not always work

Browse Source 
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)
