    editor: ensure NMACertChooser type is around
    
    The widget classes templated with GtkBuilder don't load the types they
    require, leaving their users in despair and gloom:
    
      ** (run-vpn:1094459): CRITICAL **: 11:33:54.424: file
            properties/nm-openvpn-editor.c: line 2623
            (openvpn_editor_new): should not be reached
      Error: .:4:2076 Invalid object type 'NMACertChooser'
    
    Drag this one in manually.
