/**
* Atypical gloda unit test that tests nuke migration. Gloda is not designed
* to be shutdown and started up again in the same process lifetime. It tries
* to be clever with caching accessors that clobber themselves out of existence
* which are hard to make come back to life, and probably other things.
*
* So what we do is create a global-messages-db.sqlite with an unacceptably
* old schema version before tickling gloda to startup. If gloda comes up
* with a database connection and it has the right schema version, we declare
* that gloda has successfully loaded. Our only historical screw-up here was
* very blatant (and was actually a result of trying to avoid complexity in
* the nuke path! oh the irony!) so we don't need to get all hardcore.
