Resolved issue aborting test with jasmine via PhantomJS

Weird issue when executed:

grunt test

I got:
...
Running "concurrent:ts_test" (concurrent) task

        Running "jasmine:ts_dist" (jasmine) task
        Testing jasmine specs via PhantomJS

        Warning: Cannot read property 'pid' of undefined Use --force to continue.

        Aborted due to warnings.
...

After googling solution, found a way work around:

cd node_modules/phantomjs/
npm install

Jasmine working again then.
