Title: Fix single select attribute update

Commit a99c938 broke the single select update logic a bit,
because `element.getAttribute( 'multiple' )` returns `undefined` instead of null,
so single select also used `updateMultipleSelectValue`.

I couldn't update select with numeric values, tweaked the test to show that.
