Remove :only restriction on Admin::TopicsController as there's no action in this controller that doesn't need it

```ruby
module Forem
  module Admin
    class TopicsController < BaseController
      before_filter :find_topic

      def edit
      end

      def update
        @topic.subject = params[:topic][:subject]
        @topic.pinned  = params[:topic][:pinned]
        @topic.locked  = params[:topic][:locked]
        @topic.hidden  = params[:topic][:hidden]
        if @topic.save
          flash[:notice] = t("forem.admin.topic.updated")
          redirect_to forum_topic_path(@topic.forum, @topic)
        else
          flash[:error] = t("forem.admin.topic.not_updated")
