Avoid system server crash due to package removed

Cherry-picked from aosp.

Fixes bug 18593178.

Symptom:
When application is not responding, an ANR dialog will shown.
In certain timing, user uninstall the application when the ANR
occurs, but before ANR dialog shown. The system server will crash
when looking up the errorReportReceiver because the package is removed.

Here shows how the exception occurs.
java.lang.IllegalArgumentException: Unknown package: app.package.name
