patch 8.2.1966: popup becomes current window after closing a terminal window

Problem:    Popup becomes current window after closing a terminal window.
Solution:   When restoring the window after executing autocommands, check that
            the window ID is still the same.  (Naruhiko Nishino,
            closes #7272)
