[libvirt] [PATCH] tests: fix schema checks sorting

[Eric Blake]

Commit 6fdbce12 attempted to sort the list of tests, but failed
(without quotes, echo merges all the tests into a single line,
so there was nothing to sort).

* tests/schematestutils.sh: Fix thinko in previous patch.

Pushing under the trivial rule.
