patch 8.0.0678: closing a window does not trigger resizing

Problem:    When 'equalalways' is set and closing a window in a separate
            frame, not all window sizes are adjusted. (Glacambre)
Solution:   Resize all windows if the new current window is not in the same
            frame as the closed window. (closes #1707)
