Fix the case of using a quote inside a homepage article title

[erwan-kessler]

This fix is only for the weird case that if you use a quote in the title like so

---
title: "You're the best"
weight: 30
header_menu: true
---

This in terms transform it to You're the best as a string which once evaluated by jquery gives the correct ID, thus the double escape

Hi @erwan-kessler, thank you very much for getting in touch ❤️ .

You are right; the implementation was error-prone.

In f483bba, I tried to move this logic away from the client.

Let me know, if this works for you.
