When removing all the changes associated with a user, do not bump the associated updatedOn timestamp similarly to what it does the single removal of individual drafts. Add also coverage for the existing use-cases where adding or removing a draft change should not update the updatedOn timestamp, already working but not properly covered. Bug: Issue 11325 Change-Id: Ieaad3888b570db9eee6e2eb8130acc3b4cfe3d16
