Resource instance fetch() throws when called with no arguments

Run this Sandcastle, check the (actual, browser) console. You will see

Cannot add property method, object is not extensible

Somebody, somewhere, is freezing the return value from defaultClone before options.method is assigned here, only in the case where options is undefined. As you can see in the example, passing an empty object works around this. The cheap fix would be to change L1106 to options = defaultClone(options || {}, defaultValue.EMPTY_OBJECT); but it would probably be more helpful in the long run to ensure that defaultClone can never return a frozen object.

Also, in filing this issue, I discovered that your sample data for the "GeoJSON and TopoJSON" Sandcastle demo is missing -- just open that page and try to click any button, you should get a 404.

Thanks @thw0rted! I've submitted a PR to fix this here: #6210
