Fix extra space in json list serialization (#57)

Al intentar realizar test de aceptacion: CoursesCountergetControllerShould -  new CourseCreatedDomainEvent("8f34bc99-e0e2-4296-a008-75f51f03aeb4", "DDD en Java", "7 days"). Este caso peta porque una vez ha deserializado el "value" no queda ningun extra space.
Saludos
