Mostly for Trevor--reset factors API doc.
I confirmed with Karl, this should be like the rest of the lifecycle operations, and return an empty object (that's the way it's implemented so no code change needed, just update the doc). The only exception to this rule right now is the Expire Password operation, which currently does return the complete user object.
