[Persistence] Fix bug in id filtering

Browse Source 
Fix bug when filtering out namespaced identifiers when reading
domain object models from persistence; filter operation was
breaking the logic of pairing ids back to loaded models by
index. Corrects behavior introduced to reduce latency when
loading the telemetry hierarchy, part of WARP Server
integration, WTD-644.
