Angular errors on login page are caused by loading ngdetails view.
Although registration of URL for ngdetails is executed on top level
of Horizon, ngdetails view is not needed to be loaded in login page,
i.e. openstack_auth side.
To fix this issue, this patch moves registration of URL for ngdetails
into openstack_dashboard side.
