reflog tests: test for the "points nowhere" warning

The "git reflog expire" command when given an unknown reference has since 4264dc15e1 ("git reflog expire", 2006-12-19) when this command was implemented emit an error, but this has never been tested for. Let's test for it, also under gc.reflogExpire{Unreachable,}=never in case a future change is tempted to take shortcuts in the presence of such config.
