t3510 (cherry-pick-sequencer): use exit status

All the tests asserting failure use 'test_must_fail', which simply
checks for a non-zero exit status, potentially hiding underlying bugs.
So, replace instances of 'test_must_fail' with 'test_expect_code' to
check the exit status explicitly, where appropriate.
