openvidu-deployment: Media Node health watchdog: no warm-up while openvidu.service is stopped

The warm-up after an openvidu.service (re)start also applied when the service had
been stopped, so a node whose OpenVidu was stopped soon after starting was only
replaced 15 minutes after that start. The warm-up now needs the service active
(or activating); a stopped or failed service counts as unhealthy at once.
