[bug] panic: leveldb closed in x/oracle/integration

[Unique-Divine]

Context

I encountered a strange error in a GitHub action during the integration tests.

1. Commit: 42a8b65

2. Note: I'm unable to reproduce it locally and only started seeing these errors after upgrading cometbft to v0.37.5 and changing the default db backend from goleveldb to PebbleDB

Addendum - 2025-01-10

This panic is still common in CI and happens ~30% of the time. We use pebbledb everywhere, so the integration tests sometimes fail with "panic: pebbledb: closed" due to some cleanup step happening prematurely in "testutil/testnetwork".

Error Encountered

Note from @onikonychev: Using the verbose flag, "-v", in combination with race seems to remove the condition. This still needs more validation from CI runs on main, but the hypothesis seems to be correct based on the changes from #1912

Closing this for now unless the issue resurfaces
