Add integration tests with web3

[sohkai]

We could run aragon.js against a test organization on a local chain to test the output of its observables.

We could further use aragonCLI to script actions inside the organization (e.g. executing actions, installing apps, upgrading apps, etc.) to verify the reduced state given back to clients matches what we expect.

Aragon.js is the layer between the client and the apps --> https://github.com/aragon/aragon.js

Can we get some inputs and expected outputs to write tests for?

I think this issue is already enough described. It is required to set up an e2e test environment and to test all existing features or at least creating issues for those which didn't get tested. This issue is not really a task it is more an epic of tasks. But it should have been pretty straightforward for a blockchain engineer.

I will add this task to the backlog state in Linear and we can if actually required create an epic out of it. @steffclearteam
