[FIX] im_support, mail: message with odoobot as author

Before this commit, the `author_id` of a message with odoobot was
`"ODOOBOT"`. This leads to some issues due to `author_id` being
considered as an array `[partnerID, name]`.

Because of this, mail status manager was registering a partner with
ID `"O"` (1st char of `"ODOOBOT"`) for fetching its `im_status`. Its
`im_status` was never updated, since no partner has such ID. However,
the mail status manager kept this partner flagged with missing
`im_status` and still attempted to fetch its `im_status`,
indefinitely.

This commit fixes the issue by turning `author_id` of a message with
odoobot into arrray `["ODOOBOT", "ODOOBOT"]`. That way, `author_id`
of a message is always an array, and the `im_status` of `"ODOOBOT"`
is no longer fetched.
