GigyaCore.register() account.initRegistration not passing params, ie dataCenter

[ihgvan]

The account.initRegistration API allows for passing a dataCenter parameter. This call is abstracted behind the the GigyaCore.register() method and it is not passing the params that we pass to the GigyaCore.register() method. It does pass it along to account.register. But the dataCenter param we are passing is not sent in the account.initRegistration so the created account is not created in the intended data center.
