[FIX] mail: route only to other models when routing a forward

When mailgateway receives an incoming email being a reply to a thread but
containing a recipient being an alias linked to another model, it is
considered as a forward to that new alias. It therefore skips the reply
step in routing and applies rules related to new thread, aka checking
all recipients.

Consider this use case: receives a email on a task from "project@domain"
project being the alias of the project which creates new tasks when not
routing replies. Reply / forward it to "project@domain, sales@domain" in
order to transfer it to the sales team (sales alias creates new leads).
As this is a forward, both aliases are evaluated, leading to a new task and a
lead which is not what we expect.

We solve this issue by removing alias linked to the ignored reply model
when considering recipients.
