* use controller module address instead of module name for NewMsgChannelOpenInit (cosmos#2568)

In controller keeper's `registerInterchainAccount` we execute a `MsgChannelOpenInit` to set up an ica channel. Currently, we have [`icatypes.ModuleName`](https://github.com/cosmos/ibc-go/blob/95cec44c9fb10a2e84a327cdd98c7d588f091f42/modules/apps/27-interchain-accounts/controller/keeper/account.go#L63) as the msg signer. This is not good because the [`ValidateBasic()`](https://github.com/cosmos/ibc-go/blob/692790402a033c1d9647c1e1eded5351332283bf/modules/core/04-channel/types/msgs.go#L34) of `MsgChannelOpenInit` has check if msg signer is bech32 or not.
