commit de64e7eb67b9acd46ad60cea2df2631e25285ed0

Fix MessagePopupCollection asan failure.

Rather than closing popups immediately, we should close the popups with
animation and let MessagePopupCollection::Update() close them
eventually.

Ideally MarkAllPopupsShown is problematic and this should be cleaned up
along with UiController, but for now the fix should be acceptable as it
just replicates the behavior of old MessagePopupCollection.

Steps to repro:
1. Create a notification
2. Click on a notification
