patch 9.0.0590: after exiting Insert mode spelling not checked in next linev9.0.0590

Problem:    After exiting Insert mode spelling is not checked in the next
            line.
Solution:   When spelling is enabled redraw the next line after exiting Insert
            mode in case the spell highlight needs updating.
