[FIX] website_blog: fix the date filter on the blog posts

Since [this commit], following these steps:
- Go to /blog
- Activate the sidebar option
- Select a date filter on the sidebar

=> An error occurs.
The bug comes from the fact that since [this commit], some arguments
were passed twice to a function which causes a python error. The fix is
just to not pass the same argument several times.
