historicState always returns the most recent value for DB4O persistence

[GoogleCodeExporter]

I'm on Openhab 1.0.0 on Linux and using db4o persistence to store temp values. 
In db4o.persist I have:

Strategies {
    everyMinute : "0 * * * * ?"
}

Items {
    * : strategy = restoreOnStartup
    Temp_Out : strategy = everyMinute
}

In my logs I see that the values are persisted:
23:04:00.006 DEBUG o.o.p.d.i.Db4oPersistenceService[:137] - Stored item state 
'Temp_Out' -> '18.3475'

If I query the temp values for 1 minute ago, 1 hour ago and 1 day ago using 
syntax like 'Temp_Out.historicState(now.minusMinutes(1))' I always get the last 
persisted value, not the historic value. 

I know that the values are properly persisted in the database because the 
minimumSince, maximumSince and averageSince works fine.

So there must be some bug in the historicValue for db4o.

When testing, I just always get "Uninitialized" now. Will have to analyze it in 
detail, thanks for reporting it!
