Opening installed app on AAOS images makes the session crash

[Michele Lo Russo]

- Problem description:

Session crashes when opening the app installed on an AAOS-based application.

Some more detailed info from Gary:

> This error was caused by the following patch 0004-ANBOX-set-current-focused-application-during-the-act.patch
> Which caused the app watchdog to be triggered in such a case

- How to reproduce:

1. Create an application with AAOS container image and an APK (e.g. the 1list one).
2. Create a session for that application and join it once it becomes active.
3. Open the 1list app from the app drawer.
4. See the session crash shortly after.

- System log is attached - relevant lines (thanks Gary):
