Hygiene: Simplify listener for inserting RecentChange

On review of the recent change query and formatter it became obvious
we no longer use the individual data that was provied by the individual
extending implementations of the recent changes listener.  This simplifys
it all down to a single listener.  A followup patch moves this class into
Flow\Data\Listener where it belongs.
