t2020-checkout-detach: check for the number of orphaned commits

Browse Source 
Change the test that orphans commits to leave 2 commits behind. Add a test
that leaves only one of these behind.

The next patch will truncate the list of orphaned commits earlier. With
this preliminary update, its effect will become more obvious.
