What

How

• Following steps on issue to get to the pages to be removed, and deleting both views and controllers.
• Finding any usage of Recount model and relationships on controllers and views (and removing it)
• Finally removing the Poll::Recount model and database table & indexes

Screenshots

Test

Warnings

• Many features that are present on Madrid are still not here.
• Poll::FinalRecount features will be removed on next PR to avoid too much things to review just in one (altough model will be kept for history purposes)
