When a dataset cannot be previewed in the Data Explorer - e.g. when the dataset it too large, or has not been loaded to the DataStore (e.g. http://demo.ckan.org/dataset/bad-hyperlink-example/resource/36a112c0-7a4e-40da-aa0d-8e0c67e64957) the Data Explorer is providing an incorrectly addressed "Download resource" hyperlinked button

The hyperlink URL http://demo.ckan.org/dataset/bad-hyperlink-example/resource/36a112c0-7a4e-40da-aa0d-8e0c67e64957 is missing the terminating text /download/
