Bug 493076

STEPS TO REPRODUCE
1. Have multiple displays with color management (ICC profile) configured
2. Use `powerdevil` built without `ddcutil` support (to enable plasma's color management based brightness control). The external display should use plasma's color management as its brightness source
3. Set the external display brightness to 100%
2. Set night color to "custom times" (the current state should be "evening transition", possibly reproduces with other states)
3. Reboot

OBSERVED RESULT
Night color is only activated for the internal laptop display
Re-activating night color does not enable the it for the external display
Disabling and re-enabling ICC profile for the external screen also enables night color for the screen

EXPECTED RESULT
Night color should be enabled automatically
