The previous behavior was to simply switch from the internal control to the service's control, discarding anything that was added to the playlist before binding. We now carry over the changes made to the playlist when switching controls. This means the switch is now transparent to the user. When the service's control is read-only, we cannot transfer the items, which means the user must be notified of the items that might have been "lost" during the switch. Auto-test modified to reflect this change.
