Fix applying dark scheme when QT_STYLE_OVERRIDE is set

When QT_STYLE_OVERRIDE is set to something like "Adwaita-dark" it breaks the theme since it doesn't apply the corresponding color scheme. We should check if we should force dark color sheme similarly to how it's done in GnomeSettings::styleNames(). Signed-off-by: Pavel Artsishevsky <[email protected]>
