Last block time bug

There is a small inconsistency in addition of lastBlockTime field.

Affected method is query-data
{"jsonrpc":"2.0","id":4,"method":"query-data","params":{"url": "acc://bridge.acme/audit:42161:mint:ACME"}}

lastBlockTime is embedded into result.data

In all other methods there are result.lastBlockTime (outside of result.data)
