If rendering a Cell causes an error, catch it, report the exception to Airbrake and render nothing

application.rb

# config/application.rb

unless Rails.env.development?
  Cell::Rendering::ClassMethods.class_eval do
    def render_cell_for(name, state, *args)
      cell = nil
      cell = create_cell_for(name, *args)

        parent = cell.parent_controller
        until parent.is_a?(ActionController::Base)
          parent = parent.parent_controller
        end
        parent.send(:notify_airbrake, exception)
      else
        Airbrake.notify(exception)
