ICAD tests fail when specifying > 1 validator

[chatton]

Summary of Bug

Since bumping the number of validators to 4 the icad tests seem to be timing out when broadcasting a MsgSubmitTx message.

We didn't catch this as these tests aren't run on every PR.

here is a sample failure

On a separate branch, I reset the version to 1 and ran this workflow and it passed.

We need to figure out if this is a genuine failure or if it is an issue with the test or test framework.

Can we retry these tests with increased validator set using the latest version of the go relayer? I saw an ica bug fix fixed there

Unsure if it is related cosmos/relayer#953

[colin-axner]

I can look into this

Looks like none of the new icad tags include the time.Now() fix
