HttpRequest is mangled before context function in 0.2.2

[shellicar-eagers]

Passing an HttpRequest to the handler should not result in the request getting mangled.

Behaviour before 0.2.2: context is created and returned.
Behaviour on 0.2.2: Context creation failed: Request is not an instance of HttpRequest

import { ApolloServer } from '@apollo/server';
import { v4 } from '@as-integrations/azure-functions';
import { app, HttpRequest } from '@azure/functions';

const server = new ApolloServer({
  // config
});

const createContext = async (args: v4.AzureFunctionsContextFunctionArgument) => {
  if (args.req instanceof HttpRequest) {
    return {};
  }
  throw new Error('Request is not an instance of HttpRequest');
}

const handler = v4.startServerAndCreateHandler(server, {
  context: createContext,
});

app.http('graphql', {
  authLevel: 'anonymous',
  methods: ['GET', 'POST', 'OPTIONS'],
  handler,
});

This seems to be because of this change.

Yep having the same issue here after upgrading to apollo/server v5 and as-integrations/azure-functions v0.2.2 and unable to get the request parameters

Will take a look. Thanks for the feedback.
