I had more or less the same problem but in my case the issue was intermittent and not reproducible. See:
I also saw the warning about “cordova already loaded” (logged by the ionic.io libraries).
For now I just took out the ionic.io libraries (analytics etc, at the moment these are in “alpha” stage so probably it wouldn’t be wise to use them for production apps anyway). I’ll monitor closely if I see the issue again.
