This is needed to avoid the following error when creating a new CosmWasm keeper:

Could not lock exclusive.lock. Is a different VM running in the same directory already?

By using t.TempDir as the home directory when creating the app, the CosmWasm keeper will create the lock file inside a subfolder of that directory. This will avoid any issue due to conflicts since each test creates a custom temporary directory when it's run.

I think I've done a duplicated work in #119 😓

[RiccardoM]

@hallazzang I think we can use this one. What do you think? If you see that the changes that I've made are all the ones necessary could you please accept this so that we can try running a new testnet? Thanks! 🙏

Well we need to check if these changes are just enough. Can you tell me which method did you use to do the upgrade? I see some same changes with miniwasm v0.5.x made here but not all. Did you cherry pick some commits? Cause I cherry-picked(sometimes without git cherry-pick) all changes.

@hallazzang

Can you tell me which method did you use to do the upgrade?

I've just upgraded the dependency and fixed the issues by either copy/pasting the changes or manually fixing imports and such. If you are more confident with your changes, we can use your PR. Just make sure that linting, building and tests pass fine.
