MonitorXrandr: update the internal data structures after applying

Browse Source 
We were relying on the XRandR events from the X server to update
the configuration, but we were calling meta_monitor_config_update_current()
immediately after, so the MonitorConfig would be updated with the
old configuration (and we would save that to disk!)
