BUG: When painting ctkRangeSlider, the slider groove was highlighted

There was an extra highlight in the Slider groove done by
painter.drawComplexControl(QStyle::CCSlider, option); This is because the
painting assumes the slider position is valid. Disable it by setting its
position to the minimum (left).
