Testing issues

[faddat]

• osmosis-labs/tm-db needs to be updated to match tendermint/tm-db
• osmosis-labs/iavl should run tests in CI on its own

Reason: We've created some kind of incompatibility between our tm-db and upstream. At first, I thought that it was version bumps that I made, but I've confirmed that it's not.

I think it might be that we are missing this commit:

tendermint/tm-db@9ea19a1f74b904130dfaf0709aa2c3d500b90949\

Testing that currently...
