Subject: Fixed bug creating invalid HTML in select options

When a select tag is created for a field with errors, and that select
tag has :prompt or :include_blank options, then the inserted first
option will errantly have a <div class="field_with_errors"> wrapping
it.

See https://github.com/rails/rails/issues/7017
