Title: Removing `Entity::_relationship` and refactoring `Entity::__isset` & `Entity::__unset` : WARNING BC BREAK.

Separating `Entity::_relationship` & `Entity::_updated` has imo not a good thing since they are both datas and currently such separation only work on the loading step. Indeed if I use the following syntax :

$entity->mydata = $somedata //the datas goes into _updated even if it's a relation

So I think it's preferable to remove this feature for the moment and rethink of it when it'll be really necessary.

Secondarily close #571
