Importing a npm TS module with bundled typings, when the entry is a JS file results in the TS module's typings not being recognized.
Run npm test to see the issue, which should be something like:
➜ ts-loader-error git:(master) npm test
> @ test ~/projects/ts-loader-error
> tsc && echo 'works!' && webpack
works!
