machine_options is not preserved.

Hi,

I have the following code which cannot converge because the Vagrantfile is not correct on the second convergence.

my_machine_options_for_virtualbox = <<-VC
      config.vm.provider "virtualbox" do |v|
        v.memory = "512"
        v.cpus = "1"
      end

      config.vm.box = "opscode-centos-7.1"
      config.vm.network "private_network", ip: "192.168.33.50"
    VC

# Making machines converge 1 time
    machine my-machine do
      machine_options my_machine_options_for_virtualbox
      recipe 'initialize'
    end

# Convergence second time for 'setup' without machine_options
machine my-machine  do
   recipe 'setup'
end

On the second convergence, Chef modified the Vagrantfile, erased all the vagrant config in my_machine_options_for_virtualbox. So when reloading, it caused RuntimeError

RuntimeError ------------ vagrant reload my-machine failed! STDOUT: STDERR:There are errors in the configuration of this machine. Please fix the following errors and try again:

vm:
