Clean up ComponentController and fix some bugs.

1. Only log a package-not-found error if the user has been unlocked. If
   the user is still locked, it's reasonable to get a package-not-found
   exception for persisted direct-boot-unaware jobs.
2. Actually log the cache for debugging purposes.
3. Only update the package info for the user the package changed in.
4. Also update the cache when an app is updated.
5. Clean up the cache when an app is uninstalled or a user is removed.
6. Make sure locked methods are annotated and named correctly.
