### Steps to reproduce
1. Start from fresh 11.0.2. No Apps
2. Run the updater app
I am testing the upgrade with QEMU first, starting from fresh NextCloudPi
https://ownyourbits.com/2017/02/13/nextcloud-ready-raspberry-pi-image/
here is the installation code
https://github.com/nachoparker/nextcloud-raspbian-generator/blob/master/nextcloud.sh
running it with QEMU
https://ownyourbits.com/2017/02/06/raspbian-on-qemu-with-network-access/
### Expected behaviour
1. Installation finishes ok, no warnings
2. Hitting the button to go back to your NC 11.0.3 takes you to the new instance
### Actual behaviour
1. Installation finishes ok, no warnings
2. Hitting the button to go back to your NC 11.0.3 takes you a white error screen that says
> Composer autoloader not found, unable to continue. Check the folder "3rdparty". Running "git submodule update --init" will initialize the git submodule that handles the subfolder "3rdparty"
