a11y: Realize GtkStackPage parent context before trying to get a ref

If a context is not realized, calling gtk_at_spi_context_to_ref() will
return a null ref, because its path has not been initialized yet. This
was already done for all other cases in get_parent_context_ref(), but
was missing for the GtkStackPage case.

Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4944
