The travis build script fails

[sverhoeven]

It runs tasks/e2e.sh script which when run locally fails.

Tried to fix tasks/e2e.sh script in `travis-e2e` branch.

Fails with:
```
> node packages/react-scripts/scripts/build.js

Creating an optimized production build...
Error in bail mode: [default] /tmp/gg/packages/react-scripts/node_modules/@nlesc/tslint-config-react-app/node_modules/tslint/custom-typings/resolve.d.ts:28:2
Duplicate identifier 'export='.
```

Disabled Travis-CI build for now, will enable when this issue is fixed.

Is this a bug? My builds were passing on Travis up until a certain commit. Now getting very generic error when building on Travis. Build goes fine locally.

Creating an optimized production build...
Failed to compile.

For PR #47 I enabled Travis-CI again.

Looking at https://travis-ci.org/NLeSC/create-react-app/builds/191663062

• The Node v6 builds have problems with a tslint rule, this could be corrected by Upgrade tslint to v4 #48.
• The Node v4 builds are missing Babel somehow

The method used at https://github.com/NLeSC/create-react-app/blob/master/tasks/e2e.sh#L138 to use the react-scripts package seems to have problems with the scoped package name (@nlesc/...). Switching to the method described at https://github.com/NLeSC/create-react-app/blob/master/development-setup.md to install the @nlesc/react-scripts package could be a work around.

@bryantee what is the nodejs version you are using locally?
