Title: Remove background on diff-refine-change

I think the background here was unintentional - only one of the occurrences is reversed, the rest can just inherit whatever background they'd naturally have.

In my case this was making Magit advanced diff mode look weird as the background was bleeding through the magit-item-highlight face.
