Quick fix for #790.
If a file has to be created when $::sensu::rabbitmq_cluster is true , this should be totally safe and legit.

@agoddard sorry for delay in the reply.
My fix looks a bit too trivial to me to make me feel 100% comfortable about it and I have't tested this on a real Windows server, yet.
What's the expected behaviour when $::sensu::rabbitmq_cluster has some values (hash or array)?
If a file in $conf_dir/rabbitmq.json is expected, then this should be safe and enough.

@alvagante thanks! The expected behavior is as you suggest - as long as it's set and a file is present, it should avoid the current error (No such file or directory @ rb_sysopen - \etc\sensu\conf.d\rabbitmq.json)

Thanks!
