Support variadic argument with a single item

[arakov]

Describe the bug A variadic method handler should be called if there are normal method with the same name

To Reproduce

public class A
{
   static Test(params string[] args)
   {
      console.writeLine("params:string");
   }

   static Test(string[] args)
   {
      console.writeLine("string[]");
   }
}

public program()
{
   var a := A;

   a.Test("abc");
}

Expected behavior The correct method has to be called.
