    ev-view-presentation: set goto window's parent
    
    The presentation view has a feature where if you type numbers in
    presentation mode, a text entry popup appears so you can enter a page
    number to navigate to. The popup does not correctly appear when running
    under Wayland and the console shows this message:
    
    "Window 0x562684b01210 is a temporary window without parent, application
    will not be able to position it on screen."
    
    Fix this by using the gtk_window_set_transient_for() function to set the
    popup's parent.
