The connection pages of the messaging add-ons and the connections list
show "This bot is also connected as <name>. Both connections will answer
the same message." on both connections, with a link to the other and a
"Turn this one off" button.
Saving a connection that would be a twin of another enabled one asks
first: the server answers 409 with the type duplicate_connection, and the
page offers "Save anyway", which sends confirm_duplicate.
The new texts are in all nine locales of the web UI and of the shared
connector pages.
