[PATCH 1/6] dinput8/tests: Flush events after creating window.

[Rémi Bernon]

To make it more likely it gets focused on X11 and fix spurious failures.

This is the first part of a refactoring series to wrap ANSI interfaces
around the unicode interfaces in a generic and more consistent way.

Right now simple wrappers exists, at different levels, sometimes
duplicated between the generic device base and specializations.

The goal is mostly to cleanup the code but also eventually simplify the
implementation of an HID joystick device.
