Valid denom cannot be sent via IBC

[giansalex]

gamm/pool/1 is a valid denom, ref: sdk validation
but I am getting an error when I try to send it through IBC.

code: 3
codespace: transfer
data: ""
gas_used: "0"
gas_wanted: "0"
height: "0"
info: ""
logs: []
raw_log: 'denomination should be prefixed with the format ''ibc/{hash(trace + "/"
  + gamm/pool/1)}'': invalid denomination for cross-chain transfer'

tx: null

Thanks for opening this issue, @giansalex.

Looks like we assume that base denominations do not contain /s. If a / is present in the denom, then we always expect that the denom is for an IBC fungible token and has the ibc prefix.

Looks like this would be a bug, but I would like a confirmation also from @colin-axner.

Yea that's a bug. We can change it. Appears that validation function is only used in MsgTransfer anyways. I'm not exactly sure if we even need any of the extra validation in that function. Ensuring it is a valid SDK denom should be good enough
