sql: fix a funky zone config in a test

The zone config in question was invalid (min bytes = max byte), but the
test didn't care cause it's a hacky test that happened to never validate
it. But as soon as you do unrelated changes to the system (e.g.
introduce a system zone config that inherits from another system zone
config), this test unexpectedly starts yelling.

Release note: None
