Bad function name some time

[sergeevik]

If custom jsonata function is lambda then name is useless (com.dashjoin.jsonata.Jsonata$$Lambda/0x00000217108ce4d8)

and some other place similar behavior:

all function methods ignore name parameter:

    public static<A,B,R> JFunction function(String name, Fn1<A,R> func, String signature) {
        return new JFunction(func.getJFunctionCallable(), signature);
    }

it is bad because in log i get useless error:

com.dashjoin.jsonata.JException: Argument "1" of Object "com.dashjoin.jsonata.Jsonata$$Lambda/0x00000217108ce4d8" does not match Object signature
	at com.dashjoin.jsonata.utils.Signature.throwValidationError(Signature.java:289) ~[jsonata-0.9.9.jar:na]

in example it was Signature. When create JFuntion with signature. name of function ignored for Signature

        public JFunction(String functionName, JFunctionCallable function, String signature, int numberOfArgs) {
            this.functionName = functionName;
            this.function = function;
            this.numberOfArgs = numberOfArgs;
            if (signature!=null)
                // use classname as default, gets overwritten once the function is registered
                this.signature = new Signature(signature, function.getClass().getName()); <-- class name maybe lambda
        }
