[up] treat select option value null as empty string

so to keep the option as an empty value when used inside <promise-form> or similar. This is necessary to keep the syntax consistent with Vue 2. Also explained here vuejs/docs/issues/1295 (cherry picked from commit 5dd37788cd92d3d433db005f819563fa49ff05ea)
