Add a test network setup and patch for E2E tests (#18)

- The E2E tests sometimes fail with error `timeout exceeded waiting for block` in CI (always passed locally)
- The error occurs in the test network (provided in cosmos-sdk) creation when [waiting](https://github.com/cosmos/cosmos-sdk/blob/v0.50.3/testutil/network/network.go#L622) for the first block because of block timeout being too short ([hardcoded](https://github.com/cosmos/cosmos-sdk/blob/v0.50.3/testutil/network/network.go#L670) to 5s)
- Copy over this network setup in the repo and patch to skip this check; we are waiting for a block to appear after the network creation anyway
