Protect against NPE for ActivityRecords without a stack. A previous change allowed us to remove stack that no longer contained any task. This was causing some NPE when an ActivityRecord.Token or some other cached ActivityRecord later gets converted back to an ActivityRecord and we try to access its stack. Bug: 19552874 Change-Id: Ie9454bbce56591b337f97af40f8c00b8597becdf
