Fix bug where the dynamoDBMapperRef config is not being read (#26)

The class dynamoDBTemplateBuilder is still getting reference from field dynamoDBMapperName, while when we set attribute dynamoDBMapperRef in EnableDynamoDBRepositories, field of dynamoDBMapperName will always null. It makes the application failed to startup with Error java.lang.IllegalArgumentException: 'beanName' must not be empty

Fixing by registering using the correct attribute.
