tests for wasm client migration

[faddat]

In this branch:

https://github.com/ComposableFi/composable-cosmos/tree/release/v6.3.x

We have a ci job that runs the chain for 10 mintues, which we can repurpose into an upgrade test using some combination of starship and/or cradle. The migration feels like the riskiest piece of v7, so we should make sure to rigorously test each transaction type.
