[Merge] lp:~fboucault/messaging-app/startup_time_return into lp:messaging-app

[Florian Boucault]

The proposal to merge lp:~fboucault/messaging-app/startup_time_return into lp:messaging-app has been updated.

Commit Message changed to:

Various startup time improvements (1000ms on krillin):
- do not use inline Components for dialogs and popovers.
- do not use inline Components for the empty page state
- do not use inline Component for ThreadsSectionDelegate
- do not use inline Component for SwipeItemDemo
- compile and instantiate threads scrollbar asynchronously
- conversations list: use new standard ListItem instead of custom ListItemWithActions: faster to instantiate and allows for disabling cacheBuffer
- delay compiling and instantiating bottom edge
