I've just noticed that I failed to initialized $$timed_out to zero in
PostgresNode::psql if a ref is passed for it.

Fix attached.

The tests are proving useful already; I've shown that timeline following
works great with a filesystem-level copy, but that there are WAL retention
issues (unsurprisingly) when the backup is created without slots then the
slot state is synced over by an external client.
