Increase test coverage of state rebuild (#4020)

Only run the state rebuild job if the database format version has (likely) changed.

If we have accidentally changed the format, but not changed the version,
we want to run with the old cached state, so this job fails.

If we change the state path without changing the version,
this job will take a few hours, because it will do a full rebuild.
