Cleanup user data when user stopped

1. During the quick user switch, the user status is changed from
   STATE_STOPPING to STATE_BOOTING, the process android.process.core
   (ContactsProvider2) was not closed, but the AccountManagerService
   cleanup the user in stopping stage.

2. When the user is switched back, the old ContactsProvider2
   process was used, but the client doesn't have the listener
   registered for AccountManager any more.

3. This causes the ContactsProvider reloaded again when the phone
   is connected, then duplicated contacts will show on the screen.

4. Solution is cleaning up the user data in onUserStopped.

Test: manual verification
