When a tube is deleted it's last metric values linger #22

Say tube emails has 27 jobs ready. beanstalkd_exporter will export

tube_current_jobs_ready{tube="emails",...} 27

We restart the beanstalkd server and never create that tube again. On the next call to list-tubes emails wont be there anymore and we wont update any of its metric values. tube_current_jobs_ready will still be 27.

It will only stop being exported when beanstalkd_exporter is restarted.

But prometheus will retain its value for the retention period.

Also happens if you delete jobs one by one fast (had 60k jobs remaining after a delete procedure). A restart fixed it.
