Jeff King 9157c5cb09 t0020: use modern test_* helpers
This test contains a lot of hand-rolled messages to show
when the test fails. We can omit most of these by using
"verbose" and "test_must_fail". A few of them are for
update-index, but we can assume it produces reasonable error
messages when it fails.
