Remove out-of-date comment about scoped style resolvers.

Collecting features is not longer connected to StyleResolver and the
comment is no longer correct in any way. The nullptr test is still
there because a TreeScope may have stylesheet candidates which do not
have style sheets. A candidate is causing the TreeScope to be added to
the active list, while it has to have at least one active stylesheet to
enforce a ScopedStyleResolver instance.
