Fix pjlink issue (#20510)

Browse Source 
* Fix issue #16606

Some projectors do not respond to pjlink requests during a short period after the status changes or when its in standby, resulting in pypjlink2 throwing an error. This fix catches these errors. Furthermore, only the status 'on' and 'warm-up' is interpreted as switched on, because 'cooling' is actually a switched off status.
