* Better explain limitations of DQL "DELETE" (#9281)

We think the current documentation does not stress these details enough, so that they are easily overlooked.

* Put actual value instead of index inside $originalEntityData. (#9244)

This fixes a bug with redundant UPDATE queries, that are executed when some entity uses foreign index of other entity as a primary key. This happens when after inserting related entities with $em->flush() call, you do the second $em->flush() without changing any data inside entities.
Fixes GH8217.
