… constructed (#1407)

* fix: only send client updates when necessary and when msg is properly constructed

Previously in the relayer we were attempting to send a `MsgUpdateClient` when `needsClientUpdate` was true, as determined in the `shouldUpdateClientNow` method, without considering if the message was properly constructed in `assembleMsgUpdateClient`. This adds a check in `trackAndSendMessages` to ensure we only attempt to send the msg when a client update is necessary AND the `MsgUpdateClient` was properly constructed.

* fix: undo previous check in `sendBatchMessages`

* chore: update cometbft-client to v0.1.0

* chore: update cometbft-client to v0.1.0 in e2e tests

…in halt in Go cosmos cometbft (#1398)

A vulnerability in CometBFT’s validation logic for `VoteExtensionsEnableHeight` can result in a chain halt when triggered through a governance parameter change proposal on an ABCI2 Application Chain. If a parameter change proposal including a `VoteExtensionsEnableHeight` modification is passed, nodes running the affected versions may panic, halting the network.
