Per earlier comment, think it makes sense to early return here...And DCHECK that
suggestions_summary_list is empty.  Then you can also remove the
"suggestions_summary_list->GetSize() > 1" check at the bottom - being stand
alone is more a property of the message, with special formatting, rather than a
property of only having one suggestion.
