Title: Avoid a complete update of properties "collectionLike"

Adding an item to a collection-property (by POST to URL like ```"/{repository}/{id}/{collectionProperty}"```), the entire collection is regenerated.
Spring DATA does this by deleting all the entities in the collection and subsequent reintegration, one item at a time, producing one DELETE command (for all the items actually in collection) and N + 1 INSERT.

Similarly, removing an item from the collection produces one DELETE command and N - 1 INSERT.

Is it a desired behavior?
Otherwise I suggest commited changes.
