notes tests: don't ignore "git" exit code

Change a fragile test pattern that's been with us ever since these
tests were introduced in [1], [2] and [3] to properly return the exit
code of the failing command on failure.

Because of this I'd marked this test as passing under SANITIZE=leak in
[4] and [5]. We need to remove those annotations as these tests will
no longer pass.
