Default initscript does not remove pid file after successful stop

The SysV initscript:

https://github.com/elastic/logstash/blob/master/pkg/logstash.sysv

Does not clean up the pid file when logstash is stopped. This is unlike the initscript for redhat and debian.
This is causing issues for us as we have puppet ensuring logstash is stopped because we have migrated to filebeats. The problem is as follows:
1. Pid file exists with old logstash pid.
2. Any new process is started which just happens to have the same pid as the old logstash service.
3. Puppet kills the new process
