Ts-jest: Importing from node_modules that contain Typescript causes SyntaxErrors

[bmajz]

• Issue

We have some internal modules that contain Typescript and transpiled Javascript. When importing code from a module like this from node_modules (i.e. installing a private npm package), the imported code doesn't transpile properly and causes the following Syntax Error:
SyntaxError: Unexpected token export

However, when the same code is loaded from a directory outside of node_modules, it works fine.

• Expected behavior

These modules can be imported into tests and there is no Syntax Error

• Link to a minimal repo that reproduces this issue
  https://github.com/bmajz/tsjestissue

• Optional (but highly recommended) - Configure Travis (or your favorite system) with the minimal repo

This allows potential solutions to be tested against the minimal repo. This saves everyone time and avoids a lot of back and forth.

@bmajz the PR I've sent to the repo you've linked should fix this. If not, let me know and I'll reopen this
