No recentchange entry inserted for new topics

The lifecycle handler to insert recentchange entries
for all newly inserted posts was failing due to it
being unable to find the related workflow.

The workflow itself was set to be the last item to insert
on new topic creation in e2ce5191532308aa2101de115b83f87a7f1af8e9
to fix another bug, but that created this bug.

This time arround use DeferredUpdates to allow all the inserts to
happen and then do our housekeeping later in the request.
