Applied changes of "refactored architecture"

The angular clickstart project is broken. I guess its due to the refactoring of the angular seed project. After installing the clickstart project on cloudbees the created build fails with:

   + node_modules/.bin/karma start test/karma.conf.js --no-auto-watch --single-run --reporters=dots,junit --browsers=Firefox
[31mERROR [config]: [39mFile /scratch/jenkins/workspace/angular-seed-project/test/karma.conf.js does not exist!
Process leaked file descriptors. See http://wiki.jenkins-ci.org/display/JENKINS/Spawning+processes+from+build for more information
Build step 'Execute shell' marked build as failure
Finished: FAILURE 

It turns out that the architecture of the angular seed project has been refactored. The karma.conf.js has been moved from the "test"-folder to the root folder and protractor.conf.js has moved to "e2e-tests". 
See https://github.com/angular/angular-seed/commit/0847b751c221516f04e1d02f38ae34c0e7873f4e)

Hence, this pull-request which I believe will fix the problem.
