HTMLFormElement::ConstructEntryList() creates a FormData instance

instead of taking an empty FormData as an argument.

- This matches to what the specification says.
  https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#constructing-form-data-set
> 1. If form's constructing entry list is true, then return null.

- We avoid to create unnecessary FormData instance in a case where
  FormData::Create() throws an exception.
