[FIX] mail: automatically consider messages sent as read

Problem was that since rev. 617968c61, we consider sent messages as read client
side. This has been done to avoid to indicate that a channel has unread
messages e.g. when this channel is a follower of a chatter in which we wrote
a message.

This change has as consequence that we don't perform the 'channel_seen' RPC for
messages sent. At each refresh, the server sends information about pinned
channels, especially the unread counter, which was thus sometimes incorrect.

This rev. simply doesn't take messages we wrote into account when computing
the message_unread_counter field.

Also correctly display the 'New messages' separator in threads, by automatically
skipping messages we wrote (i.e. it is now displayed above the first message m
with m.id > last_message_seen_id and such that we aren't the author of m).
