In an initial install, the following is a potential rule ordering:
```
Notice: /Stage[main]/Zulip::Supervisor/File[/etc/supervisor/conf.d/zulip]/ensure: created
Notice: /Stage[main]/Zulip::Supervisor/File[/etc/supervisor/supervisord.conf]/content: content changed '{md5}99dc7e8a1178ede9ae9794aaecbca436' to '{md5}7ef9771d2c476c246a3ebd95fab784cb'
Notice: /Stage[main]/Zulip::Supervisor/Exec[supervisor-restart]: Triggered 'refresh' from 1 event
[...]

[...]

[...]
Notice: /Stage[main]/Zulip::Process_fts_updates/File[/etc/supervisor/conf.d/zulip/zulip_db.conf]/ensure: defined content as '{md5}96092d7f27d76f48178a53b51f80b0f0'
Notice: /Stage[main]/Zulip::Supervisor/Service[supervisor]/ensure: ensure changed 'stopped' to 'running'
```
The last line is misleading -- supervisor was already started by the
`supervisor-restart` process on the third line. As can be shown with
`zulip-puppet-apply --debug`, the last line just installs supervisor
to run on startup, using `systemctl`:
```
Debug: Executing: 'supervisorctl status'
Debug: Executing: '/usr/bin/systemctl unmask supervisor'
Debug: Executing: '/usr/bin/systemctl start supervisor'
```
This means the list of processes started by supervisor depends
entirely on which configuration files were successfully written out by
puppet before the initial `supervisor-restart` ran. Since
`zulip_db.conf` is written later than the rest, the initial install
often fails to start the `process-fts-updates` process. In this
state, an explicit `supervisorctl restart` or `supervisorctl reread &&
supervisorctl update` is required for the service to be found and
started.
Reorder the `supervisor-restart` exec to only run after the service is
started. Because all supervisor configuration files have a `notify`
of the service, this forces the ordering of:
```
(package) -> (config files) -> (service) -> (optional restart)
```
On first startup, this will start and them immediately restart
supervisor, which is unfortunate but unavoidable -- and not terribly
relevant, since the database will not have been created yet, and thus
most processes will be in a restart loop for failing to connect to it.
