monitor-conifig-manager: Generate primary monitor config with others

Browse Source 
Primary monitor is just the same of the other monitors, but it has a
primary monitor flag. Since the computation of the scaling isn't
dependent anymore on the computed configuration we can now generate the
primary monitor config together with the others.

However, we've to ensure that the primary monitor is the first of the
configs list in order to properly compute the positioning.
