[gnome-boxes/init-shared-folders] app, spice-display: Populate Shared Folders while connecting

[Felipe Borges <felipeborges src gnome org>]

commit 1de3c5bf1b5b6668d769c49f380f07302b1c7c6a

    app, spice-display: Populate Shared Folders while connecting
    
    Boxes was failing to list the users' shared folders for a machine
    because we were initializing the shared folders manager and setting
    the Spice Webdav channel shared_dir only when the Properties dialog
    was created. Now we initialize this when connecting to the machine.
    
    Fixes #372
