Bug in dictionary equality

[sm-g]

this test fails

       public void Test()
       {
           var dico1 = new Dictionary<int, string>() { { 1, "uno" }, { 3, "tres" } };
           var dico2 = new Dictionary<int, string>() { { 1, "uno" }, { 3, "tres" }, { 4, "quatro" } };

           var byValue1 = new DictionaryByValue<int, string>(dico1);
           var byValue2 = new DictionaryByValue<int, string>(dico2);

           Check.That(byValue1).IsNotEqualTo(byValue2);
       }

For anyone who also ran into it - you may use my ByValue library, which have no such issue (see these tests).
