[PATCH] d3d8/tests: Flush events after sending SC_MAXIMIZE.

[Zebediah Figura]

For some reason, on fvwm2 sometimes focus_window will be restored and activated
between the subsequent call to SetForegroundWindow() and the next call to
ShowWindow(SW_RESTORE), causing the next test to fail. Flushing first seems to
reliably work around this.

I don't know why this occurs. The messages sent suggest that a WM_STATE is
received from fvwm2, and this triggers handle_wm_state_notify() to call
SetActiveWindow() and send SC_RESTORE. But it's not clear why WM_STATE would be
sent at that point. I can't reproduce the problem on my end more than once in a
large number of times, so debugging is rather difficult.

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
