JSON content not handled properly.

[ggb667]

Doing:

const server = require("../../server/server");
const supertest = require('supertest');
const upr = require('supertest')(server);
process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";//No CA for our certs.
...
        upr
          .post(apiPathInfo)
          .set('Accept', 'application/json')
          .send(requestBody)
          .end(function (err, res) {
            if (err) {
              return done(err);
            }
            res.statusCode.should.be.equal(201);
            done();

There is a bug in cache.js. If chunk on line 145 is a object with properties, the next call return new Buffer(chunk) will fail. You can test for json and fix it with

          if((chunk && typeof chunk === 'object' && chunk.constructor === Object)){
            for(var prop in chunk) {
              if (chunk.hasOwnProperty(prop)) {
                chunk = JSON.stringify(chunk);
              }
            }
          }

If you do, it exposes another bug - now the body of requests are showing as "body": {},
instead of having content (so the actual calls fail, even if they are not in the cache). Turning off replayer shows the calls completing normally.
