One of the tests was to make sure that the `ArrayHandleMultiplexer` is working in the exec environment. It was doing this with an `ArrayCopy`. However, the `ArrayCopy` was falling back to the host, so the test was not doing what was expected. Now use `DeviceAdapterAlgorithm::Copy` to force the array to work on the device.
