As Setup.php assigns variables based on the cache config, bootstrap.php was late on reseting them, as some objects were already created.
So we could end up with a SqlBagOStuff created there, which when later accessed (such as trying to invalidate the cache for a user) would
-as any non-sqlite SqlBagOStuff- open a new db connection. Which is precisely what we shall not be done when dealing with temporary tables
(and would indeed fail miserably due to not finding unittest_objectcache table).
In summary, reenabling temporary tables disabled in r79411.
lack of fuzz testing and other parser test options, and the DB creation is still a little flaky.
A MediaWikiPHPUnitCommand class had to be created to allow for custom CLI parameters.
