Can't successfully rerun the cookbook if set the wrong parameter the first time

[lanqisong]

If the first time I set the wrong parameter e.g node['rabbitmq']['address'] , the cookbook exited when restarting the rabbitmq.
Then second time I corrected the node['rabbitmq']['address'], and rerun the recipe, it will exited before the reconfigure the rabbitmq-env.conf file. Because the recipe will try to start the rabbtimq before reconfigure at this line: https://github.com/jjasghar/rabbitmq/blob/master/recipes/default.rb#L115-L117

It looks like we repeat that line per the case statement. It'll probably be a good idea to pull it out and put it at the bottom of the recipe.

I'll put together a PR today of what i'm suggesting, and maybe you could test it?
