[PATCH 2/6] dinput8/tests: Add some HID joystick IDirectInput8_CreateDevice tests.

[Rémi Bernon]

Creating a device with the instance guid may get the wrong one if a
true controller is plugged in.

This is because driver_hid.dll runs in a different process from
winehid.sys, and so gets another set of rawinput handles.
