    gschem: redraw empty preview on configure events [#2159047]
    
    If the preview widget contained an empty page, the redraw failed. In
    the preview_event_configure() function the function a_zoom_extents()
    returns without drawing if there are no objects on the page. Thus I've
    added a complement logic to redraw the background of the preview if
    required.
