vim-patch:8.2.4341: command line not redrawn when finishing popup menu (#21792)

Problem:    Command line not redrawn when finishing popup menu and the screen
            has scrolled up.
Solution:   Redraw the command line after updating the screen. (closes vim/vim#9722)

Code change is N/A as Nvim doesn't call update_screen() here.
