Description

Reverted #7579 because I was getting: panic: ConsensusState PublicKey is not crypto.PubKey

Tested:

gaiad tx ibc solo create myothersolomachine 2 solomachine.json --from slippery --node http://159.65.118.186:26657 --chain-id slippy-0

@colin-axner Is this ready for merge? We're planning to cut 0.40.0-rc1 tomorrow, and it seems like its important to get revert backported, as #7579 is already in the rc1 backports PR (#7590).
