Fix redrawing of mode lines when exposed (Bug#19721)

 src/dispnew.c (adjust_glyph_matrix): Set the update_mode_line flag
 of the window whose current glyph matrix was resized, which
 disables the mode-line row as side effect.
 src/xdisp.c (redisplay_window): Don't avoid redisplay of a window
 whose update_mode_line flag is set.
