Fix modes not restoring mode-line when disabled

Seems in some odd cases where {global-,}hide-mode-line-mode is
interactively disabled, the mode-line isn't always entirely redrawn when
mode-line-format is restored (i.e. force-mode-line-update is
insufficient). This causes the restored mode-line to remain invisible. A
forced redraw is needed.
