Work around Cite reset issue

The Cite extension does not currently handle resetState calls in
sub-pipelines, and relies on sharing a single Cite instance between all
pipelines. Fixing this is a longer project, so this patch works around the
issue for now by passing a flag indicating resetState calls in sub-pipelines
and ignoring the call in Cite in that case.
