update get all speeches to not have a request body

[ed42311]

in routeHandlers.js

  getSpeech: function getSpeech(req, res){
    Speech.find(req.body, function(err, savedSpeech){
      if (err) return res.status(500).json(err);
      res.status(200).json(savedSpeech);
    })
  }

Speech.find should take no params or an empty object, i.e. { }
