Subject: [PATCH] core: make sure "systemctl reload-or-try-restart is actually
 a noop if a unit is not running

This makes sure we follow the same basic logic for try-restart if we have a try-reload.

Fixes #688

(cherry picked from commit 3282591dc30b2934a895c7403d2f0b0690260947)
Resolves: #1191920
