[FIX] website_slides_survey : fix certification badges display

Before this commit, when going to /profile/ranks_badges on the website,
an error 500 happened when it had to show certification badges.
This is because the certification badges use the "state" field of their linked
survey to check if it is still open.
This field has been removed in 15.0, where the active state of the survey is
used to know if it is still used instead of a state.  When archiving a
certification survey, their linked badge is automatically archived as well,
so there is no need for that line anymore.
