Systemsettings - display orientation not updated when enabling/disabling second monitor (minor)

[Roger Light]

I have a primary monitor in landscape mode, and a secondary monitor in portrait mode, rotated 90 degrees anticlockwise.

* Open system settings and go to display configuration
* Select the secondary monitor
* Uncheck "Enabled"
* Click Apply
* Check "Enabled"
* -> Secondary monitor reappears in UI, in landscape mode
* -> Orientation button "90 degrees anticlockwise" is still selected
* Click Apply
* -> Secondary monitor is enabled, but in landscape mode

I would expect the monitor orientation buttons to be consistent with the orientation displayed on the UI.

This is a pretty minor bug, clicking "90 degrees anticlockwise" does update the UI, so it's easy to work around.
