/v2/flush not flush redis db

[suraneti]

Describe the bug I've debugged when a transaction has succeeded and cfg-web POST /v2/flush to cgw-web but the Redis db is still not flushed. This makes a UI never be updated and needs to manually flush with redis-cli.

To Reproduce Steps to reproduce the behavior:

• curl

  curl -v -X POST   -H "Content-Type: application/json"   -H "Authorization: Basic secret"   -d '{ "invalidate": "Chains" }'   http://nginx-service:8000/cgw/v2/flush

• cgw-web logs

  [2023-05-22T09:26:20Z INFO  rocket::server] POST //v2/flush application/json:
  [2023-05-22T09:26:20Z INFO  _] Matched: (post_flush_events) POST /v2/flush application/json

Expected behavior Redis db should be flushed, a UI should be updated after a tx is completed.
