In this page, there are 3 items flickery when back from conversation
page,
- The summary under priority conversations
- The summary under non-priority conversations
- The clear all button under recent conversations
This is because there is no key on these 3 preferences, when preference
screen updated in onResume(), preference screen thought these 3 are new
items, shows an animation for them. Add keys to them to fix.

By moving loading in each controller to the same thread.
There will still be shifting as the conversation prefs are added, but it
won't be the over thte top shift up and shift down motion that existed
prior to this cl.

Since the button for clearing recent conversations may still
exist after the user triggers the button since some of the
conversations might not be removable

- Don't show the button if nothing is clearable
- Optimistically remove preferences on pressing clear since the actualy
clear action is asynchronous
