customizing hl-line-face should reset global-hl-line-overlay to nil

[Drew Adams]

Customizing `hl-line-face' has no immediate effect. You must save the
customization, quit Emacs, and restart Emacs, to see the effect.

This is because customizing it does not delete the overlay. It is
enough to set `global-hl-line-overlay' to nil, to see the face change,
but customization of `hl-line-face' does not do this. It should.
