REPO-1204 / MNT-16742: getChildren returns duplicate nodes

Browse Source 
- fallout from MNT-12894
- noticed by customer when iterating via CMIS getChildren with no explict sort order
- we need to put back an implicit sort order, if none is specified
- note: todo - we could consider optimising further for those use-cases where maxItems is greater than a pre-configured threshold (eg. > 1000) and we don't expect to sensibly page through that many results
