Change a fragile pattern introduced in 696acf45f9 (checkout:
implement "-" abbreviation, add docs and tests, 2009-01-17) to check
the exit code of both "git symbolic-ref" and "git rev-parse".
Without this change this test will become flaky e.g. under
SANITIZE=leak if some (but not all) memory leaks revealed by these
commands are fixed.
