AngularJS tests are currently always failing as PhantomJS doesn't seem to start up correctly.
Seems there was a new release of Karma (6.0.0), which causes the problem. As we are currently requiring Karama
>= 0.12.1 only, it automatically used the new version for testing.
I've added a
< 6.0.0 for the Karma requirement. This ensures the version 5.2 is used again.
Will merge this for now, so tests are running again.
