```ruby
RSpec.configure do |config|

  ### This helper is required because servers.get(id) does not work
  def get_server(connection = nil, id)
    connection ||= compute_connection
    connection.servers.filters = {'instance-id' => ["#{id}"]}
    connection.servers.first
  end
end```

Fix the helper method to get server based on id.
