Bug Description

Steps to reproduce:
* Reboot device (or kill ubuntuappmanager)
* stop unity8
* start any application

Current results:
* input is lost for all subsequent non-system sessions

Expected results:
* input works for non-system sessions

Notes
* starting any app before having stopped unity8 (or started it, for that matter) obfuscates the issue, as input works correctly then.

This is problematic as it can easily break autopiloting apps if there has not been an app launched before stopping untiy8.

Some real-life steps:

* reboot phone
$ adb shell
  $ sudo -u phablet -i
    $ initctl stop unity8
    $ ubuntu-calulator-app

Input lost.

Passing --desktop_file_hint doesn't help.

Another workaround seems to be to unlock the greeter before stopping unity8.

I can reproduce this. After running the unity8 test suite there's no input in apps.
