deleting token on confirmation
better tests
Re-write conversation confirmation view to delete token in the POST request if confirmation is successful and to render the confirmation template directly instead of redirecting to the GET request (this removes some of the hackiness).
Log inability to find tag info for a message as info rather than error since it can happen once per message currently if a conversation is prematurely closed. Leave TODO to log it as an error (this code might not survive the new endpoint routing anyway).
Fix typo in fallback delivery_class type.
Rather fall back to original transport type in transport type isn't one understood by Go currently -- this at least generates useful errors (review by @jerith).
