fix(didRender): force didRender on revisiting same route

[sarbbottam]

using a hidden {{link-to}} to force re-render

fixes #2

---

I noticed, that if there is a {{link-to}} component present in the template, the component is re-rendered on visiting the same route.

Same can be witnessed in the dummy app.

After loading:

• Click "Topics"
• Click "Topics"
• Click "Topics"
• ...
• Observe focus state set at the "Topics" level every time.

Thus added a {{link-to}} component wrapped in a div with style display:none.

Using display:none on an element will not only hide it from the display but will also remove it from the accessibility tree.

This will cause the element and all its descendant elements to no longer be announced by screen reading technology.
