Work around race condition focusing a window on a different workspace

Browse source 
When we focus a window on a different desktop, and the calc_showing
idle that hides/shows the windows gets run before we get focus events
back from X, we think that we are hiding the window with the focus
so we focus a "random" window to avoid leaving the user with no focus.

Work around this temporarily by checking display->expected_focus_window;
this isn't a perfect fix because there are cases where
display->expected_focus_window corresponds to a window we tried to
focus in the past but failed, but it makes things work fairly well.
