	The test as added in 79ec651a286c71a3d4c72be33a1f80e76a560031 had no effect: first because ‘guix time-machine --commit=X’, not followed by a command, does nothing, and second because the “! COMMAND” shell stanza does not have the desired effect (see <https://issues.guix.gnu.org/62406>). This change rewrites the test to make it effective. * tests/guix-time-machine.sh: Rewrite.
