Malformed getapplicationlog RPC request result #897
Description
Describe the bug
While testing the nspcc-dev/neo-go#3402, I discovered that ApplicationLogs plugin returns improper result of getapplicationlog RPC call. The result contains wrong contract field value of notifications section. For example, getapplicationlog for genesis block of mainnet has exactly the same notification's contract hash for all notificaitons (for both OnPersist and PostPersist triggers), 0xd2a4cff31913016155e38e474a2c06d08be276cf (native GasToken). While I'd expect contract hashes of notifications to have proper values.
This bug was introduced in master after 20th of March, because in that day I successfully built neo-modules master and checked genesis block notifications within the scope of neo-project/neo#2834 (comment). I'm suspecting that this bug was introduced by #865, because this PR was merged 21th of March and makes a lot of changes in ApplicationLogs plugin, but we need to check.
To Reproduce
Steps to reproduce the behavior:
- Build fresh neo-modules master and fresh NeoCLI;
- Run NeoCLI with RPCServer and ApplicationLogs plugin enabled and start mainnet sync from genesis;
- Send
getapplicationlogRPC request to RPC server with genesis block hash; - Check the result.
The result from the fresh master is:

Expected behavior
The expected result is mentioned in neo-project/neo#2834 (comment), it should have proper contract hashes for all genesis notifications:
