Removed assertion. I'm not entirely sure why it was there, but it was preventing Gorm running (along with anything else that provided categories on subclassed classes). I need some more testing to make sure that this didn't break anything else, but Gorm now runs correctly with the new runtime, so it seems like an improvement...
