[gtk+/places-sidebar] Go back to our machinery for Recent files instead of reading recent:/// as-is

[Federico Mena Quintero <federico src gnome org>]

commit c1c1823634b500e1266122eabbd16701a5a2786f
Author: Federico Mena Quintero <federico gnome org>

    Go back to our machinery for Recent files instead of reading recent:/// as-is
    
    Reading recent:/// as-is is probably fine for OPEN mode.  But for SAVE mode, we want to present
    a list of recent directories.  So, we go back to our old machinery for now; in the future
    we'll probably just use recent:/// and extract the list of recent directories from there.
    
    This also fixes showing the Recent item as highlighted when the file chooser starts up.
