HTMLSelectOtherFields: Have 'other' always as first element

The other field is in most case the default item selected in the drop
down box when a page is loaded. But when the last item is selected you
have to scroll to the top to select one of the first item, which are
often the common or most used items.

So adding the 'other' always as first item to the list.
For the HTMLSelectAndOtherField this was before
If4175332405d26c7ff2e8fbe100bcad61762ce6f, so that is fixing a
regression. In my opinion it should be the same for both types.
