    infobar: fix initial window position
    
    Call gtk_widget_set_allocation after chaining up to parent class
    to ensure that GtkInfoBar has correct allocation. Otherwise x and y
    is set to zero causing wrong window position in gtk_info_bar_realize.
    
    This fixes info-bar-message-types.ui reftest.
