Duplicate id in slider tooltip demo

[karenbennett]

There are 4 sliders demonstrated in http://demos.jquerymobile.com/1.4.5/slider-tooltip/

The fourth, mini version, has the same id, slider-3, as the third.

Could be fixed by changing slider-3 to slider-4 in lines 36 and 37 in jquery-mobile/demos/slider-tooltip/index.php
