Simple test-project for SystemJS issue 2336
Problem found in another repo: viT-1/systemjs-ts-es6-vue cause: import html templates as js strings into ts which is implemented by shim typings and gulp-html-to-js package in predeploy gulp script. SystemJS v5 can resolve relative generated paths in SystemJs modules from ..config.ts to html.js, but SystemJs v6 can't.
