Title:
Multi-monitor settings are lost when switching between single- and

control-center

Bug description:
Bug summary:
I set up and save the two configurations separately in gnome-control-
center for single- and extended-display modes, but they are not
applied when switching modes with Super+P (or with the dedicated key)
or when switching modes in gnome-control-center, the settings don't
persist.
The settings are saved in ~/.config/monitors.xml when setting up and
saving the configuration in gnome-control-center, but they are not
applied when switching with Super+P or when switching modes in gnome-
control-center, the settings don't persist.
Another way to see the bug is to save a mode configuration in gnome-
control-center then switch to the same mode using Super+P by pressing
Super+P many times without selecting a different mode, the settings
will be lost. See the attached screencast.
Steps to reproduce:
0. Attach an external monitor to the laptop
1. Change the fractional scaling of the external monitor to 150% and
change the positioning of the built-in monitor to the desired
positioning
2. Switch to the single-display mode using the keyboard or in gnome-
control-center
3. The fractional scaling of the external monitor changes to 100% →
(this could be the intended behaviour and not a bug)
4. Change again the fractional scaling of the external monitor to 150%
5. Switch to the extended-display mode using the keyboard or in gnome-
control-center
6. The fractional scaling of the external monitor changes to 100% →
(this is a bug, it should persist from step 1 or 4)
7. The positioning of the built-in monitor changes to the default →
(this is a bug, it should persist from step 1)
What happened:
Multi-monitor settings are lost when switching between single- and
extended-display modes.
What I expect to happen:
Multi-monitor settings should persist.
