[FIX] crm: deleting a crm.activity

crm.activity inherits mail.message.subtype with the field subtype_id
Before rendering "chatter.ChatComposer", the internal subtypes are fetched
on model mail.message.subtype(in function "fields_view_get").
But when deleting a crm.activity, the linked mail.message.subtype was not
deleted.

Used case:

When deleting a crm.activity, the activity still appeared in the chatter
if you log an internal note for an opportunity as an employee.
