Fixed issue when typescript language services do not return references

Since TypeScript 1.3 the typescript language services return no references for the following statement which I currently use in a project:
`export import Foo = require('./foo');`
I tried disabling this rule `/* tslint:disable:no-use-before-declare */` and also tried disabling tslint altogether for the file which was failing `/* tslint:disable */` but tslint called the method nevertheless and failed at calling the method forEach of undefined because `references` is not defined.
