[gnome-boxes] properties-toolbar: Drop main_back_button

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 672ed53132dcfe466ecf0512fe84d29900ac565a

    properties-toolbar: Drop main_back_button
    
    The 'Back' button in main view was only needed for wizard->properties
    case and now we don't have this UI transition anymore so this button is
    now redundant.
