Call getModalComponent after ioComponents are initialized

[chpoulter]

I noticed that IO state is not shown anymore in the UI. I'm not that deep in angular, but I think this is because modalComponent is created to early. At this point ioComponents is not filled yet.

I move it to the end into the then() of getConfig(). Now it works as expected.
