msg.ValidateBasic() does not return sdk.Result type

[truted]

msg handlers return an sdk.Result type to the API with one exception: if msg.ValidateBasic() fails, it returns something else. This is because msg.ValidateBasic() is run by the cosmos framework before the msg is processed by the registered handler.

This results in the following two formats being returned by the API, the first is what ValidateBasic() returns and the second is what the handler returns if an error occurs:

"{\"codespace\":\"claim\",\"code\":101,\"message\":\"Invalid claim body, too short: \"}"

"[{"msg_index":0,"success":false,"log":"{\"codespace\":\"claim\",\"code\":102,\"message\":\"Invalid claim body, too long\"}"}]"

Bonus: we can remove this code from modules:

	// if err := msg.ValidateBasic(); err != nil {
	// 	return err.Result()
	// }
