Fix leaks of personal apps in setApplicationHidden

* If setApplicationHidden is called with a non-system
  non-installed app, the exception thrown exposes
  whether the app is installed on the personal side.
* To solve this, the exception thrown is wrapped
  and a different message, which does not include
  whether the app is installed, is used.
