Revert "reduce memory capture in http logger"

This reverts commit fc2e043b20204e04f240814d4efc05762db7df96.

Had to revert this because req.route.path is not set until a matching
route has been hit, so it was always null inside res.end meaning
statsd data was never sent over.

This commit did not actually stop the memory leak so reverting it
has not short term repocusion
