update image for meteor 1.6

[aboire]

Meteor 1.6 uses the 8.8.1 version of node and npm 5.4.2

[abate]

same problem here. it fails with this error :

=> Starting meteor app on port:80
/app/programs/server/boot.js:50
    const { pause } = require("./debug.js");
          ^

SyntaxError: Unexpected token {

that I'm pretty sure it's node related.
