[facet js] fix reordering of facet check boxes. Closes #2732947 Before this patch, when one select an element, it's moved to the top of the select content. Fine.

This patch fixes that by introducing a facetCheckBoxReorder function which properly reorder the whole facet, instead of buggy attempt to locally reorder.
