Never call ReCreateMenuBar inside a menu event handler

As of wxWidgets 3.2, the wxWidgets event handler runs code after the
the client event handler that depends on the menu still existing.
Because there are potentially many paths to call ReCreateMenuBar from
within a menu event handler, let's just wrap this action in a CallAfter
to make sure it happens after the wx handler call completes.
