ibc: fails when unpack ClientState

[yihuang]

Summary of Bug

Do ibc-transfer using cli without passing --absolute-timeouts, it fails with error message:

AssertionError: Error: cannot unpack Any into ClientState *types.Any: failed unpacking protobuf message from Any

Version

0.40-rc3

Steps to Reproduce

• start devnets connected with ibc
• setup connections/channels with relayer
• do a ibc-transfer with cli:

  chain-maind tx ibc-transfer transfer transfer demo0channel $receipet 1000denom --home data/ibc-0/node0 \
    --node tcp://localhost:26657 --keyring-backend test --from relayer --chain-id ibc-0 \
    -y --packet-timeout-height 1-2000 --packet-timeout-timestamp 0
  

  error message:

  AssertionError: Error: cannot unpack Any into ClientState *types.Any: failed unpacking protobuf message from Any
  

• Add flag --absolute-timeouts, then works fine.

Thanks for opening this issue. Looks like the command is failing after trying to get the client state from the passed in channels

Most of our cli commands are untested and need some fixing, ref #6392
