monitor-manager-xrandr: Re-work xrandr event handling

Browse source 
In randr events, configTimestamp can be considered the hotplug time,
i.e. whenever the server notices hardware changes, this value will be
updated.

Having that in mind, we can re-work the logic to make it clearer.
There are no semantic changes.
