Intellisense does not pickup Typescript 3 references

[tommedema]

• VSCode Version: 1.26.1
• OS Version: OSX High Sierra

Steps to Reproduce:

1. git clone git@github.com:tommedema/serverless-mono-example.git
2. cd serverless-mono-example && yarn install && code .
3. if you change a typing in package random, it is not picked up by intellisense in typescript packages that reference to it in the same workspace (e.g. sls-random); you'd have to compile first

for example, change fetchRandomNumber in random to return a Promise<string>, and sls-random still expects a Promise<number>

Note that sls-random is connected with random through Typescript 3 references:

{
  "extends": "../../tsconfig.settings.json",
  "compilerOptions": {
    "outDir": "dist",
    "rootDir": "src"
  },
  "references": [
    { "path": "../random" }
  ]
}

And therefore intellisense should pickup the referenced typings dynamically.

Does this issue occur when all extensions are disabled?: Yes
