[FIX] website: use absolute href location after page url change

Before this commit:
When editing a page URL through page properties it would redirect to that new
url afterward. If the url was not starting with '/' and had multiple level
before and after edition (eg: page/action to page/realaction) it would then
redirect to a wrong relative URL.

Now, we ensure that we redirect to the correct URL: the one slugified and
cleaned in the backend.

Step to reproduce:
  - Create a page '/page/action'
  - Go to that page and open Page Properties
  - Edit the URL to 'page/someaction'
  - You will be redirected to the incorrect relative URL /page/page/someaction
