The second test called "detect incorrect generation number" asserts that we correctly warn during an fsck when we see a non-zero generation number after seeing a zero beforehand.
The other transition (going from non-zero to zero) was previously untested. Test both directions, and rename the existing test to make clear which direction it is exercising.
