recipes/server.rb should honor parameter node['mysql']['version']

I've been using the mysql cookbook from vagrant, but the version parameter was not taking affect.  After adding a test to make sure recent changes to account for ubuntu 14.04 were working (the tests passed), I found the issue could be fixed in server.rb. 

I'm pretty new to chef, vagrant, and ruby, so maybe I'm doing something wrong.  But this is how I was invoking the cookbook from vagrant:


		vm.provision :chef_solo do |chef|
			chef.cookbooks_path = "cookbooks"
			chef.add_recipe "mysql::server"

			chef.json = {
				:mysql => {

					server_root_password: rootPassword,

					version: '5.6',
					port: '3306',
					data_dir: '/data-mysql',
					allow_remote_root: true,
					remove_anonymous_Users: true,
					remove_test_database: true
				}
			}
		end	

Before the change to server.rb, I was getting MySQL version 5.5.  After the change I get 5.6 as expected.
