Create end-to-end type test

[dstaley]

It would be nice to have a single file that runs through all the various methods to ensure that types can pass between methods as expected.

For example:

const client = new KintoClient("http://server.com");

const createBucketResult = await client.createBucket("name");
const bucket = client.bucket(createBucketResult.data.id);

const createCollectionResult = await bucket.createCollection("things");
const collection = bucket.collection(createCollectionResult.result.id);

const createRecordResult = await collection.createRecord({ petName: "Jpeg" });
const updatedRecord = await collection.updateRecord(createRecordResult.data);
console.log(updatedRecord.data.pet);
