Check and fix usages of error type ErrInvalidMsg

[webmaster128]

In an error ack I got error code 10, which is documented as

	// ErrInvalidMsg error when we cannot process the error returned from the contract
	ErrInvalidMsg = errorsmod.Register(DefaultCodespace, 10, "invalid CosmosMsg from the contract")

However, it seems like the error ErrInvalidMsg is used in places where no contract created CosmosMsg is in case, such as

func (msg MsgUpdateAdmin) ValidateBasic() error {
	if _, err := sdk.AccAddressFromBech32(msg.Sender); err != nil {
		return errorsmod.Wrap(err, "sender")
	}
	if _, err := sdk.AccAddressFromBech32(msg.Contract); err != nil {
		return errorsmod.Wrap(err, "contract")
	}
	if _, err := sdk.AccAddressFromBech32(msg.NewAdmin); err != nil {
		return errorsmod.Wrap(err, "new admin")
	}
	if strings.EqualFold(msg.Sender, msg.NewAdmin) {
		return errorsmod.Wrap(ErrInvalidMsg, "new admin is the same as the old") // <---- should not be ErrInvalidMsg
	}
	return nil
}

For other usages of ErrInvalidMsg it would also be good to double check if "invalid CosmosMsg from the contract" is the correct definition.

I just double checked and to me it seems that the only case where usage was not proper was solved in #1311.

Fixed in #1317 for v0.32
