Default genesis state missing for ibc module

[sahith-narahari]

The current implementation of ibc module has nil for default genesis state but validates the genesis with unmarshal. This prevents creating a valid genesis state in current master

The exact source of issue can be found here

cosmos-sdk/x/ibc/module.go

Line 55 in 97e1c31

@fedekunze @jackzampolin is there not supposed to be a DefaultGenesis for IBC?

[fedekunze]

There is, we need to export clients, channels, connections, sequences, etc. It's already on master 👍

[aaronc]

Should we reopen this then?

GenesisState for IBC was already implemented. It's on master
