[gnome-photos/wip/rishi/collection: 16/21] embed, source-manager: Show notifications for mounts present at startup

[Debarshi Ray <debarshir src gnome org>]

commit cb23e7a79c7ab37185f041d6f0d6b2baed75c8a9
Author: Debarshi Ray <debarshir gnome org>
Date:   Fri Jan 12 09:52:21 2018 +0100

    embed, source-manager: Show notifications for mounts present at startup
    
    Unlike GoaObject-backed sources, GMount-backed sources can be
    synchronously enumerated during start-up. However, this means that
    SourceManager::notification-show will be emitted too early for Embed to
    catch it.
