Nit: For consistency, we could probably change these conditionals to look like
the unconditional reset() calls in operator=() below.  (The reverse change
wouldn't be safe as they need to be unconditional in operator=().)

Actually, to satisfy both performance & consistency, I've moved this code to the
constructor's initialization list.

     associated_keyword.reset(new AutocompleteMatch(*match.associated_keyword));
+  if (match.search_terms_args.get())
+    search_terms_args.reset(
+        new TemplateURLRef::SearchTermsArgs(*match.search_terms_args));
