Sorry, I committed as the wrong author. Now amended but don't know if that will clear the CLA whinge.

I fixed all the authors and (I think) accepted the CLA under the erroneous author email but that check still won't pass. Please just review this on its technical merits and accept anyway if OK - there are tests now.

Author on one of the commits is different than your github id. I'll just merge this as you have signed the cla with your github account.
