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 &lt;https://issues.guix.gnu.org/62406&gt;).

This change rewrites the test to make it effective.

* tests/guix-time-machine.sh: Rewrite.
