Update the Edit dialogue on contact linking or unlinking

Ensure any open Edit dialogues are:
 • closed, if they're editing the details for a meta-contact which is then
unlinked; or
 • reloaded to show the details of the new meta-contact, if they're editing
the details for a contact which is then linked.
