remove-unlisted-plugins = true seems to remove plugins listed under plugins juju config before reverting and bringing jenkins back up

[moon127]

The charm config option "remove-unlisted-plugins" when set to true is intended to ensure plugins removed from charm juju config are removed and jenkins restarted.

However any time plugins are updated via juju config this setting seems to wipe all plugins before restoring, which causes unnecessary downtime:
