This PR changes type checks for the request bodies for the student and educator signups to be non-strict. This means that undefined is an acceptable value for nullable fields (since null == undefined but null !== undefined). Ultimately, this means that requests don't need to include these fields in their bodies, rather than being forced to explicitly set values to null.
