i've found the issue -- postmodern backend creates its "system" btrees
(like root, schema-table etc) in "fancy" way, so it cannot simply 
deserialize
them if something in DB refers to it, so it depends on object cache.

but some tests call flush-instance-cache, so db-postmodern gets broken.

i'm not sure what is the idea behind "special" btrees.. probably it will
work fine without this special stuff, but i'd prefer not to touch them :),
so i'll better specialize flush-instance-cache to ensure system btrees
are cached after flush.

seems to be passing all tests now, ha!
