fixes routes

When i installed it on:

  Redmine version                2.4.1.stable
  Ruby version                   2.0.0-p247 (2013-06-27) [x86_64-linux]
  Rails version                  3.2.15

After successfull voting i had:

"Error executing the poll macro (No route matches {:controller=>"polls", :action=>"reset_vote", :poll_id=>#<VotingPoll id: 1, project_id: 11, question: "Устраивает ли нас система голосования?", created_on: "2013-12-16 09:30:47", revote: true>, :project_id=>11, :back_url=>"/issues/15"})"

Fixed it.
