Enable history comparison in ref-tests

Previously ref-tests just ignored the scrollback history to keep
the old tests working, this would lead to new tests which rely on
scrollback history to succeeed even though they should not.

This has been fixed and it is now possible to create ref-tests with and
without scrollback history. When available the scrollback history is
compared, but the old tests still work without having to adjust them.

This fixes #1244.
