Review request for Akonadi, Kevin Ottens and Volker Krause.


Description
-------

If there are not synchronized folders in the resource, a call to ImapResource::retrieveItems( const Collection &col ) fails (and prints an "Got incomplete ancestor chain.." error message), due to the missing rid.
The call to retrieveItems is caused by FetchHelper::triggerOnDemandFetch() in the akonadi server, during an ItemFetch operation. The actual itemfetches don't cause a call to retrieveItems as they correctly deliver the data from the database.
I don't think we can/should avoid the call in the server.

Maybe the rid check should go to ResourceBasePrivate::slotSynchronizeCollection( const Collection &col ) instead (which is what I think gets called by triggerOnDemandFetch in the end), but according to volker resources may also completely ignore the rid, thus making the call to retrieveItems without rid valid.
