Previously, we queried for the extra view's stats during the rebuild. The full rebuild can take an arduous amount of time. By moving the background calculation outside of the rebuild code path, we can load the stats in the background and update the view outside of the app loading cycle. Bug: 35144044 Test: Manual -- this was race condition-y, so I just tested several times. Change-Id: Id2f92e32c3b3f9c5d5cf4a7308cca38c2e52789c
