Requests at root [/] crash the converter

Example spec

openapi: 3.0.1
info:
  title: Example API
  version: 1.0.0
paths:
  /:
    get:
      summary: Example operation
      description: ''

Description

Calling convert on a spec like the one above produces the following error:

TypeError: Cannot read property 'push' of undefined
    at Node.addMethod (/Users/brpeterm/workspaces/ApiSetup/src/ShopbopApiSetupScripts/node_modules/openapi-to-postmanv2/lib/trie.js:25:19)

    at Object.convert (/Users/brpeterm/workspaces/ApiSetup/src/ShopbopApiSetupScripts/node_modules/openapi-to-postmanv2/index.js:10:14)

The problem is here:

openapi-to-postman/lib/util.js

Lines 274 to 276 in d344eed

	trie = new Trie(new Node({
	name: '/'
	})),

The root node of the trie does not have anything in requests, so the first attempt to add a request to it throws this error.
