As a developper
I want to separate running tests from building in all our angular apps
So that our CI job "Build and run" does only one job and stops running javascript test when we already have a separate CI job for that.

Moreover, we should have npm scripts to build and test our apps instead of relying on running grunt: e.g. 'npm install && npm run build' should minify our app without running tests and 'npm install && npm run test' should run unit tests and produce a junit test results file.
This lets us remove our global dependency on grunt on the CI server and makes it easier to change the command line that is run (without changing the CI job).
