Fixing search to search for the go server in the expanded run_list

[keymon]

If you enable agent "autoregistration" without the go server attribute, the current search query will fail with this error:

Net::HTTPServerException: 400 "Bad Request"
    from /opt/chef/embedded/lib/ruby/1.9.1/net/http.rb:2633:in `error!'
    from /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef-11.10.4/lib/chef/http.rb:140:in `request'

    from /usr/bin/chef-shell:23:in `<main>'

Actually the problem is that the problem is that the search query should be escaped twice because uses double quotes:

search(:node, "chef_environment:#{node.chef_environment} AND run_list:recipe\[go\:\:server\]")

vs

search(:node, "chef_environment:#{node.chef_environment} AND run_list:recipe\\[go\\:\\:server\\]")

But a second problem is that run_list:recipe\\[go\\:\\:server\\] will only search in the original run_list, so you can not use roles or wrapper cookbooks. The right syntax should be:

search(:node, "chef_environment:#{node.environment} AND recipes:go\\:\\:server")

I fixed it and this is the PR. I bumped the version because I need it right now, hope is OK with you.

I am adding a test now using chef-zero, adding a new suite. Lets see if it works and I will send a second PR.
