MsgSubmitBadSignatureEvidence no signer

Surfaced by @xlab in our fork.

The msg for submitting bad signature evidence doesn't require any signature for itself. That means the chain can be spammed by myriads of transactions with this msg, and no gas fee will be applied

Worth mentioning: the only msg from Cosmos SDK that follows this pattern is MsgCreateDog.
