[FIX] mail: fix mail.mail default values collision

This commit cleans the default_* keys of the context before creating mail.mails
and mail.notifications when notifying the record by email.

Without this change, there can be a collision when the ORM tries to compute
default values for the state field (for example):
- Model "A" has a 'state' field ;
- Create an action that redirects to model "A" form view, setting some default
  values in the context such as {'default_state': 'done'} ;
- Model "A" has an inherit on 'mail.thread' and a 'user_id' field to set a
  responsible user ;
- Model "A" record is created with a responsible user, who is automatically
  notified by email that the record "has been assigned to him" ;
  (see mail_thread#_message_auto_subscribe_notify)
- A 'mail.mail' is in turn created ;
- The 'mail.mail' model ALSO has a 'state' field, and the context is propagated
  so the ORM will try to assign 'done' to that field, which is an incorrect
  value ;
- -> Crash.

If we ensure that the default_* keys are cleaned from the context, the default
values computation of the mail.mail record will not be affected and everything
works fine.

A test was added to ensure this behavior.
