Subject: [PATCH] Fix UserNotificationAction::createStackable()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Use `uksort` instead of `usort` as the keys of the array are
userIDs instead of simple ascending numbers.

This fixes up commit 8518f3636eae69065e52ff7c75208ed34fa6f87c
„Working around a few possible deadlocks by sorting values“
