We don't really *need* those objects in the database after the manager (simply in the memory-managed SQLAlchemy session is good enough), and since the objects are still transaction-held, they can't be accessed by the listener hooks even if they are in the database anyway. I also took the oppertunity to turn all listener method to class methods instead. This doesn't really make any difference (the manager does not hold instance-level values), and we need at least some of the methods to be class-level (for the internal API), and it's more consistent to have them all be class-level.

Some flushes still needed for tests. The dataset object cache should still flush, but only exactly one is needed for all missing datasets, instead of one for each.
