Title: Logistration: Include course ID in analytics events for login/registration

[ECOM-625](https://openedx.atlassian.net/browse/ECOM-625): Segment authentication and registration events don't record the course id in the label property

Changes:
* The client now sends an `analytics` parameter to the server, containing additional info to be included in analytics events. The login/registration models populate this with the value of the `?course_id` querystring param, if one is provided.

* I also fixed an indentation issue in the JS test specs, so this diff looks bigger than it actually is. You can view the diff without these whitespace changes here: https://github.com/edx/edx-platform/compare/will/combine-reg-login-form...will/logistration-include-course-in-analytics?expand=1&w=1
