fix: query on stream with time partition (#886)

version v.0.9.0 - time partition was stored as Utf-8
in version 1.3.0 onwards - time partition is now stored 
as TimestampMillisecond. After migration, time partition 
gets converted from Utf-8 to TimestmapNanosecond

fix is to match TimestampNanosecond to create the time 
filters for query
