[PATCH 03/25] t: use sane_unset() rather than 'unset' with broken &&-chain

[Eric Sunshine]

These tests intentionally break the &&-chain after using 'unset' since
they don't know if 'unset' will succeed or fail and don't want a local
'unset' failure to fail the test overall. We can do better by using
sane_unset(), which can be linked into the &&-chain as usual.
