Removed use of try because it's rails only and we already protect against bulb being nil

```ruby
 def dump_summary(duration, example_count, failure_count, pending_count)
    super

    if @bulb.nil? # protect against bulb being nil
      puts "\nWARNING: Couldn't find build bulb"
      return
    end

    if failure_count.zero?
      @bulb.write "g"
    else
      @bulb.write "r"
    end

    @bulb.close
  end
```
