Counter metric is reset when it has no labels

6

Hello, I implemented a custom MongoDB metric data store. While testing it, I noticed that counters with no labels are reset every time I relaunch my application. This does not...

So I thought I'd finally have a go at the refactor I described in the massive comment added to `spec/examples/metric_example.rb` in 9f7603bef92dd5f382bb47c509454feef957dd00. I spent the first chunk of my time...
