GTK: Fix broken borders in gtk-theme in incognito mode.

We generating some tints after we computed other values that used those
tints. We also used the current color instead of the default colors (the frame
image was the default color).

BUG=52815
TEST=In gtk mode, open an incognito window. Look at the border. The color should be continuous. (Some themes require taking a screenshot and look at the color magnified to see the previous bug.)
