Fix crash when selecting AppInfo for uninstalled app from Recents.

When an app is uninstalled, the corresponding app info is not removed
fromi the Recents tasks. If user selects that app info entry from the
recents tasks, it will failed to retrieve the app detail as the package
is already removed.

Add the package removed event listener in InstalledAppDetails such
that when the package has been unintalled, its app info task will also
be removed from Recents.

Fix app info crashes when package is uninstalled from terminal.

Move start listening to the package removed intents to onCreate()
and continue listening throughout the whole lifecycle of the activity so

Fix crash in Storage app info when the corresponding app is uninstalled
in the background.

1. Move the handling for package removal from InstalledAppDetails to
AppInfoBase so that all app info subclass will now finish
correspondingly if the package is uninstalled.
2. In InstalledAppDetails, when handling package removal, will also
finish the app info fragment that it starts earlier.
