[Bug]: spoon.support.util.SortedList.addAll(...) return value is not JLS compliant

[CoreRasurae]

Describe the bug

According to Java JLS/API docs we see that:
https://docs.oracle.com/javase/8/docs/api/?java/util/Collections.html
addAll(...) Returns:
true if the collection changed as a result of the call

However in spoon.support.util.SortedList.addAll(...) calling addAll(...) on an empty collection returns true, even though no actual change was made in the collections and secondly, if some element fails to be added, despite some of them are added will return false, when at least one object was inserted in the collection, and thus the collection was modified.

It should also be noted that LinkedList which SortedList extends always inserts all elements and returns true. It only returns false if no element could be added and that if some problem occurs at the middle of an insertion of multiple objects, an exception will be thrown.

We propose the following patch:

Thanks for the patch! I agree with the inconsistency. Would you be able to submit a pull request with this patch and a test case that would cover this patch?
