These tests manually coerce the exit code of invoked commands to "success" when they don't care if the command succeeds or fails since failure of those commands should not cause the test to fail overall. In doing so, they intentionally break the &&-chain. Modernize by replacing manual exit code management with test_might_fail() and a normal &&-chain.
