Always call runtime.reset() in App.resetCart()

I think this is technically the right thing to do, just in case the wasm start function or WASI _start/_initialize functions read from memory and then set some global variables (I don't know why they would, but they could.) Probably wouldn't be necessary if we fixed the global variable problem, maybe?
