[bug] Blacked monitor swapping on wake up

[TuTAH1]

To reproduce:

1. Black 2nd screen
2. Systemly off the screens ([go to Control Panel\Hardware and Sound\Power Options\Change plan settings\turn off display, set "1 min" and wait for 1 min OR launch nircmd with parametrs monitor off] AND wait 3-10 seconds until monitors lose signals and auto-turn off.)
3. Wake them up (move mouse)
4. If 2nd screen wakes up erlier than 1st screen (for me, it's always the case), the 1st monitor will wake up darkened instead of 2nd; if you press Alt+1, the second black window will appear on 1st screen; if you press Alt+2 instead, the black window will be gone and anything will work as usually.

Solutions:

1. Easier: Check and reapply black windows when some of the monitors change its order.
2. More reliable: Store the monitors IDs instead of order and apply black windows by IDs.
