fix: use upgrade_ctx in upgraded_client/consensus_state for querying proof

[Farhad-Shabani]

Description

In PR #1153, we've made it so that client upgrade query endpoints now give us proof of inclusion along with the response. But when we ran integration tests in basecoin-rs, I found out we have to call the get_proof on upgrade_ctx to get that proof. This PR fixes this issue.
