Subject: [PATCH] network-connection-editor: Close the editor when
 nm-connection-editor exits

Previously, when editing a connection that doesn't have native editor
support, nm-connection-editor is spawned to do the work. But after
closing nm-connection-editor, an empty editor dialog still exists.

Fix that in this commit.
