Multiple continuesFroms lead to stackoverflow in IE8

[thecapdan]

This is a regression since v0.15.4.

If I am testing a PresentationModel and I have a acceptance tests that contain mutliple continuesFroms, running the tests in IE8 results in a stackoverflow alert.

The failure can be reproduced by adding the following test to our presenter library ATs and running the test in IE8

(function() {
    var GwtTestRunner = require("br/test/GwtTestRunner");
    GwtTestRunner.initialize();

    ddescribe("multiple continue from using a PresentaionModel with an EditableProperty", function() {

        fixtures( require("br/presenter/PresenterFixtureFactory") );

        it("new test", function()
        {
            given("demo.viewOpened = true");
            then("demo.model.plainProperty = 'a'");
        });

        it("new test 2", function()
        {
            given("test.continuesFrom = 'new test'");
            then("demo.model.plainProperty = 'a'");
        });

        it("new test 3", function()
        {
            given("test.continuesFrom = 'new test 2'");
            then("demo.model.plainProperty = 'a'");
        });

        it("new test 4", function()
        {
            given("test.continuesFrom = 'new test 3'");
            then("demo.model.plainProperty = 'a'");
        });

        it("new test 5", function()
        {
            given("test.continuesFrom = 'new test 4'");
            then("demo.model.plainProperty = 'a'");
        });        

        it("new test 6", function()
        {
            given("test.continuesFrom = 'new test 5'");
            then("demo.model.plainProperty = 'a'");
        });   

        it("new test 7", function()
        {
            given("test.continuesFrom = 'new test 6'");
            then("demo.model.plainProperty = 'a'");
        });   

        it("new test 8", function()
        {
            given("test.continuesFrom = 'new test 7'");
            then("demo.model.plainProperty = 'a'");
        });              

        it("new test 9", function()
        {
            given("test.continuesFrom = 'new test 8'");
            then("demo.model.plainProperty = 'a'");
        });  

        it("new test 10", function()
        {
            given("test.continuesFrom = 'new test 9'");
            then("demo.model.plainProperty = 'a'");
        });  

        it("fresh test", function()
        {
            given("demo.viewOpened = true");
            then("demo.model.plainProperty = 'a'");
        });  

        it("fresh test 2", function()
        {
            given("demo.viewOpened = true");
            then("demo.model.plainProperty = 'a'");
        });  

        it("fresh test 3", function()
        {
            given("demo.viewOpened = true");
            then("demo.model.plainProperty = 'a'");
        });  
    });
})();

I tried reproducing this in a GWTestRunner UT (without presenter) using multiple continuesFroms and I was unable to reproduce the stackoverflow

tests using verifier have sped up dramatically in IE8 following this fix + we no longer get a stackoverflow.
