Describe the bug
When you use function.addEventSource(new S3EventSource(...)) or bucket.addObjectCreatedNotification(...) it creates a BucketNotificationsHandler lambda function with some placeholder code.

To Reproduce

    const bucket = new Bucket(this, 'TestBucket');
    const lambda = new Function(this, 'TestFunction', {
      code: Code.asset('./test-src'),
      runtime: Runtime.NodeJS10x,
      handler: 'index.handler',
      description: 'Example function',
    });
    lambda.addEventSource(new S3EventSource(bucket, {
      events: [EventType.ObjectCreated],
    }));

Expected behavior
Should only connect the TestFunction to the lambda function not create a new placeholder function.
