0.16.12 breaks karma-jspm

[lookfirst]

I have no idea what changed, but now I'm getting errors running tests on my CI server (circleci)... this was all working fine before, nothing changed on my end other than jspm... =(

This was due to stricter handling of the baseURL setting - baseURL does need to be set from the first System.config call in SystemJS.
