headerbar: fix leak of start_box/end_box

Browse Source 
gtk_widget_destroy() removes widgets from their container.  However
_internal_ widgets must be unref'ed using gtk_widget_unparent() instead.
This is symmetric with the fact that these widgets were ref'ed by direct
call to gtk_widget_set_parent().  It's also the method that was used in
gtk_headerbar_destroy().
