[CURATOR-436] getSortedChildren() should ignore NoNode exceptions
getSortedChildren() should ignore NoNode exceptions and just treat it as if there are no children. This works around issues with container nodes, parents not yet created, etc.

> There is a similar looking ticket at https://issues.apache.org/jira/browse/CURATOR-358 but that dealt with LeaderSelector whereas this exception seems to be caused by LeaderLatch and LockInternals.
> Let me know if more details and/or logs are needed.
