[FIX] website_profile: make the pager work when searching

Before this commit, following these steps:
- Have more than 30 users
- Go to /profile/users/
- Search for a letter that is in the +30 users names
- Go to the second page of search results

=> We lose the filtering of the users by the letter. This commit allows
to keep the filters when the user is on a result page and changes page.
