Support for serverless >= v1.33.0

[cyrill62]

The example doesn't work with serverless 1.36.3.

The server start then exits immediately.

Running :

cd example
npm install serverless
sls graphiql && echo $?

Produce :

Server listening on: 8000
0

node : v6.16.0, v8.15.0 npm : v3.10.10, v6.4.1

I'd tested with serverless 1.29.0 and i do not have this issue.

Thanks @cyrill62, I'm taking a look at this. So far seems to be 1.33.0 where the issue first came up.
