Multi-monitor - Launch Bar is lost on "Mirror Mode" after connect the HDMI/VGA monitor to restart or switch displays mode.

Steps to reproduce:
1. Connect to HDMI/VGA monitor,
2. switch display mode
3. Find launch bar is lost on "Mirror mode".

Expect:
There's launch bar exists in monitors.

Result:
There's no launch bar exists in internal monitor and external monitor.

Note:
due to:
https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/950160
there's a switch_monitor script to help switch the mode

#!/bin/bash

# call gnome-settings-dameon xrandr plugin for handing video mode switch
# the only parameter is timestamp, I use 0 here because g-s-d ignore it anyway.
