    medialibrary: Create the label for the project settings infobar once
    
    This fixes a Gtk warning:
    
    (pitivi:3): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to
    underallocate GtkInfoBar's child GtkRevealer 0x28d2f80. Allocation is
    443x46, but minimum required size is 396x76.
