Incorrect resolution with methods with params[] array

[metoule]

This is a regression due to my PR #193. When there are two overloads that have the same arguments except for the params array, calling the method without the array leads to the improper method to be chosen.

internal static class Utils
{
  public static int WithParamsArray2(string str, Exception e) => 6;
  public static int WithParamsArray2(string str, Exception e, params string[] args) => 7;
}

var target = new Interpreter();
target.Reference(typeof(Utils));

var str = "str";
var e = new Exception();
target.SetVariable("str", str);
target.SetVariable("e", e);

// incorrectly uses the overload with the params array
Assert.AreEqual(6, target.Eval("Utils.WithParamsArray2(str, e)"));
Assert.AreEqual(7, target.Eval("Utils.WithParamsArray2(str, e, str, str)"));
