Merge auth business logic layers together

[lingqingmeng]

Requirements

• When user refreshes the page or opens a new tab they stay logged in

Notes

• We know in repo SGM the following codeblock is in config/express.js therefore OAuth2 tokens are going to be stored in sessions too

  app.use(session({
    secret: config.secrets.session,
    saveUninitialized: true,
    resave: false,
    store: new MongoStore({
      mongooseConnection: mongoose.connection,
      db: 'depor'
    })
  }));
