chef-rewind usage issue

How to unwind this template using chef-rewind?
https://github.com/opscode-cookbooks/tomcat/blob/master/providers/instance.rb#L157-L158
 template "#{new_resource.config_dir}/server.xml" do
  source 'server.xml.erb'

The chef-client run expands that to :
  template[/etc/tomcat6/server.xml] action create
  
Following the chef-rewind docs, I assumed that this would work in my recipe:
  chef_gem 'chef-rewind'
  require 'chef/rewind'
  include_recipe 'tomcat::default'
  unwind "template[/etc/tomcat6/server.xml]"
  
But it does not:

Chef::Exceptions::ResourceNotFound
----------------------------------
Cannot find a resource matching template[/etc/tomcat6/server.xml] (did you define it first?)
