gtk/dialogs: Destroy the window promptly on finish async function

Some bindings (GJS!) could add temporary references to the GAsyncResult
argument that we return, and thus to the GTask, which may cause the
dialog not to close when the finish function is called (but at garbage
collection instead!).

To prevent this, just manually destroy the window (by removing the task
data), so that we are not bound to the GTask lifetime anymore.

Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/5741
